Similarly, Scottish First Minister Alex Salmond has partly made the case for a "Yes" vote being about ridding Scotland of Conservative government.
And his deputy, Nicola Sturgeon, has accused PM David Cameron of "struggling to locate that part of his anatomy" which would see him go head-to-head with Mr Salmond in a TV debate. (Ms Sturgeon's advisers assured me at the time she was referring to the prime ministers "guts". Or lack of)
Claim and counterclaim
Scotland's economic health has been a hot topic in the campaign
How much better off will people in Scotland be? Will public services be better or worse? What does Scotland need to be an international player?
These are all questions the two sides have sought to answer with a dazzling array of figures.
And not content with punting their own views, the two sides resorted to attacking each other for dodgy sums.
Mr Salmond said the Treasury's calculations had been "blown to smithereens" because they'd already been caught cooking the books, while Chief Secretary to the Treasury Danny Alexander accused SNP ministers of offering voters a "bogus bonus" because their version hadn't taken all the factors into account.
Expect plenty more stats chat in the weeks ahead, as the campaigns continue to seek to put forward their economic arguments.
The prospect of a stronger Scotland within the UK has formed a key part of their argument, but the SNP government has questioned their ability to deliver and says the nation needs real independence.
'Mibbes Aye, Mibbes Naw'
Both sides of the campaign have been going after undecided voters
If you are an undecided voter, the campaign machines are coming your way.
Those who have yet to decide whether their "X" is going beside "Yes" or "No" are hugely influential because they're open to persuasion - and polling data for the last few months indicates "don't knows" make up anywhere between 12% and 29% of the electorate.
Supporters of the Union have also looked to history.
During a time which has seen big world war commemoration events, David Cameron used a conference speech to pay tribute to a Scottish ancestor, Captain John Geddes who died in battle in 1915, but showed "extraordinary heroism" in representing Britain standing together "when the chips were down".
And what might the two sides of the campaign make of the 2014 Commonwealth Games, being held this summer in Glasgow?
It is one of those international events in which Scotland competes in its own right.
But if you're heading to any sporting events in Glasgow between the end of July and the start of August, expect to at least see a few Yes Scotland and Better Together flyers.
Barack Obama made an unexpected intervention in the debate over Scotland's future
As one-time US defence secretary Donald Rumsfeld once noted: "There are known knowns, there are things that we know that we know. We also know there are known unknowns, that is to say we know there are some things we do not know.
"But there are also unknown unknowns, the ones we don't know we don't know."
The referendum campaigns may well be planning every last second of their strategies, but not knowing who might be next to put their head above the parapet will keep them on their toes right up until polling day.
The boss of the energy company which operates Scotland's two nuclear power stations has told staff of "continuing uncertainty" about what independence would mean for the power sector.
EDF Energy's chief executive Vincent de Rivaz said the company is not "policy neutral" and it is his responsibility to defend its interests.
In an email sent to employees across the UK, Mr de Rivaz lists the key questions which will face the company in the event of a Yes vote.
They include the regulation of the nuclear industry, the future of Britain's single electricity market and who would pay for the eventual decommissioning of the power stations at Hunterston and Torness.
Energy minister Fergus Ewing said the Scottish Government has already set out its position on the issues raised.
"Polling analyst and political gambler" Mike Smithson (@MSmithsonPB):
New post. Why Ipsos-MORI's final #IndyRef poll could be the one to watch out for tomorrow night http://bit.ly/1uF8sDA
The Press and Journal reports: "SNP environment minister Paul Wheelhouse and Scottish Green Party co-convener Patrick Harvie announced yesterday that an independent Scotland will bid to hold the annual UN climate talks.
"The annual talks bring together world leaders and diplomats with climate experts to help tackle climate change.
"This year's talks will take place in Lima, Peru, in December."
Deputy First Minister Nicola Sturgeon has said a Yes vote on Thursday will help Scotland "secure jobs and opportunities for our young people" for years to come.
On a visit to Steel Engineering in Renfrew, she said the powers of independence would prevent people having to leave Scotland to find work.
She said: "If we have our hands on the levers of economic decision-making, if we have access to our own resources, then we are able to design an economic policy to suit our needs.
"Too many young people in Scotland leave every year. Now, seeing the world is not a bad thing to do. But many people leave because they can't find a job and we need to do something about that."
Rugby players from Stornoway, on Lewis, have been discussing how an independent Scotland might affect the future of the British Lions team.
One said: "Whatever the outcome, we'll all still be friends the next day - hopefully".
She said: "This is a discussion document not a decision document. I'm part of a Government that has protected the revenue budgets of the health service and will continue to strive to do that.
"It's a discussion document written in the context of the status quo, not in the context of independence."
Tonight's the night! Switch on to @BBCNewsbeat's #bbcindyref debate at 2100 with @edibow & @itschrissmith
Gordon Brown adds: "Nobody should be told that they are any less patriotic or proud of their country.
"I want the best for this country."
Mr Darling adds: "Two days away and Alex Salmond is still refusing to answer basic questions about what independence would mean. He can't explain what would happen if firms start moving their headquarters away from Scotland, south of the border.
"And they don't need to do this, they don't want to do this. They are being forced to do this because of the uncertainties created by Alex Salmond's lack of answers."
Criticising Mr Salmond on the currency issue, Mr Darling says: "He can't even tell us what money we will be using two days before we go to the polls and it's not surprising that people are scared about that.
"What could be more scary than not knowing what currency we would have if we vote for independence?"
Gordon Brown says: "For months the Scottish National Party has said the issue is independence or no change.
"For months we have been saying that the real way to change is not to separate off Scotland but to have a stronger Scottish Parliament.
"Yes we need change but I think people are going to come to the conclusion what they want is the Scottish Parliament as part of the UK."
Robert Peston warns Scottish voters in his blog that economists have no simple answer about how they should vote.
"Here is the bad news if you haven't made up your mind whether to vote for Scotland to become independent - economic analysis cannot give you the answer.
"That is partly because this dismal science is not capable of giving wholly (and sometimes even partly) accurate forecasts about the future prosperity of nations."
Former Prime Minister Gordon Brown and Better Together leader Alistair Darling are speaking to activists in Clydebank.
Mr Darling says: "We are never complacent but we go to the polls with growing confidence.
"Because our argument that Scotland is better and stronger as part of the UK is an argument that is finding more and more support from the quiet majority in Scotland. That is why I believe we will win on Thursday."
James Adams emails: It seems that we're now being offered a choice between Devo-max (awful name) and Independence lite. Both sides offering greater autonomy within a shared monetary, economic and trading union. Both promises require the backing of the UK government to work.
Iain Steven, a small business owner, emails: A pledge, a vow, a Promise even a Contract, even signed by the political masters, BEWARE, even though they are the three party leaders, it is completely worthless. They are here representing the NO Campaign, NOT their parties.
Tony and Oonagh Godfrey email: We are weary of the Murdoch inspired soundbites of the Yes campaign.eg - all is the fault of Westminster parliament or the views of business leaders who oppose Salmond's views are a set up by Cameron... We in England have no say in the matter. Surely in an unstable world we need to unite and not to return to a narrow nationalism.
BBC Scotland's economics correspondent Colletta Smith looks at what new powers are being promised to Scotland whether there is a Yes or No vote.
Dundee United chairman Stephen Thompson has given his backing for a 'Yes' vote on Thursday.
Mr Thompson said he believed Scotland is "more than capable of being a successful independent country".
He added: "A 'Yes' vote will allow Scotland to maximise its potential on the world stage.
"One of our biggest exports and assets has been our people from all walks of life, social and political background - and one of the greatest challenges we face is to grow job opportunities so more of our brightest youngsters stay and work here in Scotland.
"There is no one better placed to make the best of Scotland than the people of Scotland and no amount of negativity from the 'No' campaign or media can change that."
As Scotland's historic vote on independence nears, Radio 5 Live's political correspondent John Pienaar presents a lively round up of the latest from the campaign trail.
"Compare that [the pro-Union offer] with the revelations we've had today about funding threats to the NHS - policies and issues and decisions that the SNP has tried to keep secret during this campaign," she added.
"We have got a campaign of lies from the SNP who are trying to tell us that the NHS is under threat when in fact it is under threat from the SNP administration."
Shadow Scottish Secretary Margaret Curran has accused the SNP of "a campaign of lies" in the lead up to the referendum.
Ms Curran said: "What is particularly new in this campaign is the guarantee of a timetable because we are absolutely sure in our commitment to the Scottish people that you'll get quicker, faster, more effective change with a 'No' vote compared to the risk and uncertainty you would get with a 'Yes' vote."
Jim, Dunkeld: I run a small business, Scotland is made up of 70% small businesses, I had the self belief and confidence. I feel if there's a "Yes" vote it will bring self belief and confidence, it will encourage youngsters to go into business.
James, Bearsden: I have no problem about who comes here, [but] where are all these people going to live? Housing will be overwhelmed.
Labour leader Ed Miliband and former Prime Minister Gordon Brown will be on the campaign trail for Better Together in the central belt.
Mr Miliband is expected to say: "The will of the people of Scotland for economic and political change has been heard and we will deliver.
"Change is coming with more powers on tax and welfare for the Scottish Parliament. We will change the British state too, the House of Lords and the way we work together across our nations.
"I ask the people of Scotland to lead that change of our whole British constitution."
Business leaders have called for unity on Friday regardless of the outcome of the referendum.
The Scottish Chambers of Commerce says, whatever the result, the country must work together to drive Scotland forward.
Speaking ahead of a visit to apprentices at an engineering firm in Renfrew with Finance Secretary John Swinney, Deputy First Minister Nicola Sturgeon said: "Only a 'Yes' vote will ensure we have full powers over job creation - enabling us to create more and better jobs across the country.
"So instead of almost 40,000 young people leaving Scotland each year as is currently the case, there will be more opportunities for our young people here at home."
Ms Sturgeon will then join carers to talk about the NHS and welfare reform. She added: "With a 'Yes' vote we can ensure our NHS is protected for future generations by enshrining it in our written constitution."
In reply to Gladys from Aberdeenshire on Morning Call, James in Edinburgh emails: It is a valid point to ask if the Scottish government can set up all the departments needed. There won't actually be that many needed as the Scottish government already has most departments either set up or other departments able to take on the tasks.
In reply to Paul from Dunblane on text, Neil from Falkirk emails: Scotland has voted for the Westminster government 14 times out of the last 21 elections, not bad for a country who never gets the government the majority vote for.
The leaders of the three main parties at Westminster have signed a pledge to devolve more powers to Scotland if it votes "No". David Cameron, Ed Miliband and Nick Clegg's agreement appears on the front of the Daily Record.
The Herald says the PM would be "heartbroken" if Scotland leaves the UK, while the the Scottish Sun sees a possible omen for Thursday's poll in a cloud, shaped like a map of the UK - but without Scotland.
Alison, Glasgow: Of course Scotland will be outward looking! We want to be part of the world on our own terms, not via Westminster, whose reputation has been tainted by illegal wars and intransigence in the EU. As Winnie Ewing said - "stop the world, Scotland wants to get on!"
Ella in Dundee: So many unanswered vital questions. Lets say NO this time but come back and ask again when we have clear detail on finance etc.
The papers were passed to the BBC and The Herald by a senior NHS whistleblower, who said they had become frustrated by the argument of the "Yes" campaign that the biggest threat to the NHS comes from the UK government.
They were presented to a meeting of health board chief executives and civil servants last month and suggest the NHS is facing a £400m funding gap.
Speaking to the BBC this morning, First Minister Alex Salmond described the £400m funding gap claim as "absolutely untrue".
"Our plans show a real-terms increase in spending - the first time the health service budget has ever passed the £12bn mark," he added.
Sandy, Ayrshire: I am voting Yes. One of the main reasons for voting Yes is saying goodbye to the Westminster system of politics. I am completely disillusioned. I am not voting Yes blindly.
Gladys, Aberdeenshire: An independent Scotland will have to set up all the departments to collect all the taxes, pay all the pensions, benefits, defence. They are promising to have all this set up in 18 months - is this possible?
Earlier we featured a photograph of how of Holyrood is facilitating the world's media.
BBC Scotland's Emma Ailes has being writing on the topic - you can read her article here.
There probably aren't that many people out there who are wholly undecided in the sense that they really are not clear at all whether they are going to vote 'Yes' or 'No'.
Really, the battle is not so much about getting people who have no idea at all - there aren't too many of those - but rather those people who have got an inclination but they're still wavering. It's to persuade those people to go in one direction or the other.
Irene, Brighton. What happens if it's a dead heat? Pistols at dawn with Salmond and Cameron? That I would pay good money to see!
Paul, Dunblane: The basic tenet of democracy is that a nation gets the government it votes for. Scotland has not been a democracy for 300 years. A Yes vote changes that. A No vote and we cease to be even a country.
Larissa, Fife: I feel we are guinea pigs in Mr Salmond's experiment. An experiment that has so many extraneous variables that it is not safe to run.
John, Stirling: Surely what is now being offered should have been there BEFORE polling started? Almost 25% of electorate have already voted.
Mr Salmond concluded: "I think no-one seriously thinks that this land is not capable of running its own finances.
"All of the scaremongering is going to fall on deaf ears. We have a once-in-a-lifetime opportunity."
Mr Salmond describes the pledge signed by the leaders of the three main Westminster parties that there will be more powers for the Scottish Parliament as the "mythical package of nothing".
Asked whether an independent Scotland would have to pay more to borrow money, the first minister replies: "No, you have to have sustainable level of borrowing and debt. As far as the cost is concerned, we'll be borrowing at Sterling rates."
Asked why many companies and financial experts are criticisng plans for a an independent Scotland, Mr Salmond replies: "Many economic experts take a different view," and mentions Nobel prize-winning economist Joseph Stiglitz, who recently criticised the "scaremongering".
He claims the Scottish government is building "better schools and better hospitals" through capital funding, rather than having money "creamed off" by private companies in PFI arrangements.
First Minister Alex Salmond is live on Good Morning Scotland.
Responding to Alistair Darling's claim that the SNP is cutting NHS funds and there is a £400m funding gap, Mr Salmond says this is "absolutely untrue".
"Our plans show a real-terms increase in spending - the first time the health service budget has ever passed the £12bn mark," he adds.
Good Morning Scotland has been reporting from the Borders this morning.
Bob Burgess, deputy editor of local newspaper the Southern Reporter, said the question of boundaries and currency had been among the key issues for people in the area.
He told Gary Robertson: "We have had to expand our letters pages quite dramatically."
Coming up, have you seen or heard anything specific which has helped you decide how you are going to vote in the referendum?
From the economy to health, from business to currency, let's have your questions and your comments.
You can listen to the programme at the top of this page.
Speaking about the nature of the campaign, Douglas Alexander said: "This campaign has both energised Scotland and it has divided Scotland. There's a heavy burden of responsibility on everyone involved in this campaign to conduct ourselves in a manner that means on Friday morning, whatever the result, we can bring Scotland together and we can move Scotland forward. I hope that is an approach that will be taken by everybody."
Mr Darling told BBC Scotland: "You can have a stronger, more secure Scottish Parliament.
"Why on earth break up the entire thing? If we vote to leave, if it all goes wrong, we can't go back."
More than six out of 10 people in England and Wales believe the UK government should not enter into a currency union with an independent Scotland, according to a poll in the Guardian.
The poll also finds that 56% of those who responded would be "saddened" if Scotland votes to be independent.
Labour MP Douglas Alexander has dismissed Yes campaign claims that independence is the only way to get the government Scotland votes for.
On BBC Breakfast he said: "I've got two governments that I didn't vote for and didn't support. I've got a Scottish National Party government in Edinburgh and I've got a Conservative-Liberal government in Westminster. So the only way you always get the government you vote for is in a one-party state and I don't think anybody is recommending that."
Alistair Darling, campaign leader of Better Together, has been speaking about the NHS this morning.
He told Good Morning Scotland: "What we are saying is if we vote No, work will start on Friday morning on increased powers, particularly to raise additional funds.
"You can have a stronger more secure health service if we vote No.
"The Scottish Parliament has the power to spend money, it will have the power to raise additional money, it can borrow more."
Ms Sturgeon added: "They [the pro-Union parties] are treating voters in Scotland with contempt."
Asked if a "Yes" vote guarantees "better lives" for people in Scotland, she replied: "Independence is not a magic wand, but it is a massive opportunity.
"We can make life better, not overnight, but over time."
Deputy First Minister Nicola Sturgeon has been responding to the offer of new powers put forward by the pro-Union parties.
Speaking on BBC Breakfast, Ms Sturgeon said: "If there was a serious intention to deliver more powers, why hasn't that happened before now?
"Tory MPs, including Christopher Chope, have already said they would block more powers. If we vote No, there are no guarantees at all."
Asked if the move smacks of panic, Mr Alexander told BBC Breakfast: "I don't think there's any embarrassment about placing policies on the front page of papers with just days two go.
"I think the 'Yes' campaign are struggling. They had an avalanche of facts engulfed in assertions last week when it was announced every major Scottish bank would move their registered office to London.
"The economic risks suddenly became very real last week, and at the same time we are offering what I believe most of us here in Scotland want which is faster, safer and better change."
"That pledge, that vow that we can have faster, safer, better change is actually a vision around which Scotland can unite," he adds.
Shadow Foreign Secretary Douglas Alexander has denied the powers pledge made by the pro-Union parties has come too late in the referendum debate.
Mr Alexander told the BBC: "Here in Scotland, we have been talking about these powers for many months. What we are saying today is we can have the best of both worlds. We can have a stronger Scottish parliament but with the strength, stability and security of the United Kingdom."
Frank, Helensburgh: The party leaders DO NOT have the powers to give away extra powers to the Scots
J S Crieff: Vote no for stability not this daft idea of independence.
The Yes campaign claims the offer of further devolution signed up to by the leaders of all three main Westminster parties would give Scotland the power to raise only 30% of its taxes.
The problem all along, and this is what people would tell you privately in the "No" campaign, is that there is a very sharp argument between independence and all the risks it brings and staying with the UK.
What they didn't do early enough, some of them would say, is put forward the alternative. They came up with a phrase which they used back in June when they said '"No" doesn't mean no change'. But they weren't clear what the change would actually be.
Now they are emphasising it, now it's on the front page of a tabloid and some people think perhaps they've left this a little bit too late. And certainly it's quite difficult if you're using complicated arguments to get through to people who are first time voters, 16-year-olds, who have never voted in their life before.
Everybody's talking about it...

With the referendum just two days away, the world's media is intensifying its gaze on Scotland.
At the Scottish Parliament in Edinburgh, preparations are under way to host hundreds of journalists and news crews from around the globe.
A broadcast village with flood lights and scaffolding two storeys high has been erected in the grounds around Holyrood. From here, reporters will broadcast live.
Calum Kerr, of Yes Scotland Borders, told Good Morning Scotland: "Bit by bit I have become massively involved. It's people that have never been interested in politics, they see a genuine opportunity for change.
"It's a different challenge here, the proximity of the border adds an intensity.
"A girl said we rely on England - the Morrisons is just across the border. You will still be able to go there."
Scotland's desire for political and economic change has been heard and will be delivered, Ed Miliband will promise today.
The Labour leader will insist a "vote for 'No' is a vote for change".
Meanwhile, rival campaigners will argue independence would bring either a "golden opportunity" or "separation and risk".
With just 48 hours until voters go to the polls, Deputy First Minister Nicola Sturgeon and Finance Secretary John Swinney will be talking to apprentices in Renfrew.
Liberal Democrat MPs Charles Kennedy and Danny Alexander will be joined by MSP Willie Rennie to highlight "the positive things that Scotland and the UK have achieved together".
Shadow Foreign Secretary Douglas Alexander will be campaigning in Edinburgh's financial district.
Good Morning Scotland has been speaking to campaigners in the Scottish Borders on both sides of the independence debate.
Michelle Ballantye, for Better Together, told BBC Scotland: "I think it's a bit of a nonsense we need to be independent to be fairer.
"I think the Borders has a strong sense of being part of the UK. Our sense of connection is very strong."
The leaders of the three main Westminster parties have signed a pledge to devolve more powers to Scotland if there's a No vote.
The pledge has been signed by David Cameron, Ed Miliband and Nick Clegg and appears on the front of the Daily Record newspaper.
It includes promises of "extensive new powers" for the Scottish Parliament.
He said: "I always said right from the start of this campaign, if Scotland voted 'No' to separation, the rest of the United Kingdom would say 'Yes' to further devolution.
"If Scotland wants more devolution - and I think Scotland should have more devolution - you have to answer the prior question 'Do you want to stay in the United Kingdom?'
"And of course that wasn't just my view; that was the view of the leaders of other United Kingdom parties who all thought it was important. Let's settle the question of separation and then look at devolution."
Good morning and welcome to Referendum Live, your minute-by-minute guide to all today's news, comment and analysis from both sides of the campaign.
With just two full days of campaigning left, and with the polls so close, the stakes couldn't be higher.
