Scottish independence: How 'No' vote could change UK

While recent polls on the Scottish referendum have suggested a boost for "Yes", the "No" campaign is still in the lead. But will anything change for the UK as a whole if Scotland votes "No"?

If Scotland votes to stay in the union on 18 September, it will be business as usual, you might think. But that won't necessarily be the case.

All three of the largest parties at Westminster have promised more powers for Scotland if voters choose to remain. The Yes campaign and Scottish government have responded that the only way to guarantee more powers is to vote for independence.

Further devolution may not just affect Scotland. It has implications for politics across the rest of the UK too. Here are five possible ones:

1. 'West Lothian Max'

One major peculiarity of British politics - known as the West Lothian question - was first identified by Labour MP Tam Dalyell in 1977.

In a system of devolved government, Scottish MPs can vote on policies covering things like schools and hospitals in England, but English MPs have no say on how these are run in Scotland because the Scottish Parliament takes care of them, which has raised questions of fairness.

If more responsibilities are handed to Holyrood, the devolved areas which English MPs cannot vote on get bigger, while there are no such restrictions on Scottish (and Welsh and Northern Irish) MPs. It's "West Lothian Max", if you like.

The SNP has a clear prescription: vote for Scottish independence.

In 2012, the McKay Commission, set up by the government, found more should be done to ensure laws affecting England had the support of a majority of MPs for English constituencies.

A government spokesman said the coalition was still "reflecting" on those recommendations and "it is too early to get into speculation about what would happen after the referendum".

The Conservative Party says its policy is that of the government. A Labour spokesman said the party was "focusing on the wider question of how to devolve more power to cities and regions in order to give people more of a say".

The Lib Dems would like to see a federal structure for the UK - "home rule all round" for England, Wales, Scotland and Northern Ireland.

But the question seems to be a big concern for voters.

A recent poll by YouGov for the Herald suggests 62% of English people believe Scottish MPs should be banned from voting on England-only laws. The latest British Social Attitudes report came up with a similar percentage.

The report also shows the proportion who agree "strongly" has risen over the past decade, suggesting the issue will not go away.

2. The Barnett formula

Another problem which has foxed MPs for more than 30 years is the Barnett formula. It was devised in 1979 as a way of adjusting block grants to Scotland, Wales and Northern Ireland to spend on devolved policy areas, on the basis of population.

Scotland receives more spending per head than the UK average - but some argue there are good reasons for this, such as the difficulty of providing services to remote communities.

The largest Westminster parties agree a "No" vote should lead to more tax-raising powers for Scotland, potentially creating a situation where it gains greater control over its own revenues but retains Barnett money.

The Conservatives and Labour Party have both signalled they would preserve the Barnett formula but seek to offset increased tax revenues against the block grant.

The Lib Dems have proposed moving to "a needs-based payment system", but they accept the Barnett formula would continue until this could be agreed.

However, polls suggest many English people see the arrangement as unfair.

The British Social Attitudes survey suggests 44% of people feel Scotland gets more than its fair share of public spending.

A Herald/YouGov poll suggests that if there is a "No" vote, 56% of voters in England believe levels of public spending in Scotland should be reduced to the UK average.

Alan Trench, professor of politics at Queen's University Belfast and author of the Devolution Matters blog, says existing tensions in the system could become worse if there is further devolution and the Barnett formula is retained.

3. Wales and Northern Ireland

If Scotland gets more powers, another obvious question is whether Wales and Northern Ireland will want them too.

In Wales, there are certainly those who believe the assembly is overdue a boost. Plaid Cymru's Treasury spokesman, Jonathan Edwards MP, says: "Whatever the result in Scotland, any Westminster government that ignores the immediate need for greater powers all round for the nations of these islands is only burying its head in the sand."

Martin Shipton, chief reporter for the Western Mail, says a "No" vote in Scotland could create concern over "the fear that Scotland would get more job-creating powers and put Wales at a disadvantage".

But this does not necessarily translate into clear support for strengthening the Welsh Assembly, he says, since "people in Wales know the economy is relatively weak and has a small tax base - they would be worried that it would lead to higher taxes".

Calls for further Welsh devolution also face barriers because of "a perception of issues with delivery of services" in devolved areas such as health and education and the difficulty Plaid Cymru has had in rallying the kind of support the SNP has enjoyed, according to Shipton.

In Northern Ireland, it would be impossible for one pro-devolution party to dominate the assembly as the SNP has done in Scotland, since legally there can be no majority at Stormont.

Tony Grew, a reporter for PoliticsHome and the Belfast Telegraph, says that he doesn't think there is a widespread call for more devolution.

"The argument in Scotland is often centred on the economy, but in Northern Ireland it's clear where the subsidies are coming from. It's very difficult to make a case that Northern Ireland would be better off."

But there is real momentum behind devolution of corporation tax - the duty companies pay on their profits - and air passenger duty, Grew says, partly because Northern Ireland competes with lower rates in the Republic of Ireland.

Lord Alderdice, a Lib Dem and former speaker of the Northern Ireland Assembly, highlights "broad agreement" that corporation tax should be devolved. He says Westminster has been "sitting on it" until after the Scottish referendum, when he expects the issue will be revived.

4. Fewer MPs?

When the Scottish Parliament opened anew in 1998, it led to a cut in the number of MPs representing Scotland at Westminster from 72 to 59.

Another reduction could potentially take place in the event of further devolution, according to the Scottish Boundary Commission.

The idea that Parliament should get smaller in general is a well-rehearsed one.

The current government brought forward legislation in 2011 meaning the number of seats in Parliament will fall from 650 to 600, but this will not take place until 2018. Of the 50 seats to be abolished, seven would be Scottish.

Prof Trench says using devolution as a basis for reducing the number of MPs is "quite a dangerous idea".

"If you are maintaining a system whereby devolved governments deal with health and education policy and the UK government takes decisions on matters of national importance, it's difficult to see why there should be fewer Scottish MPs voting on, say, whether to go to war, than English MPs."

Where he does see a problem is in Wales, which is currently "significantly over-represented" in Parliament in terms of population.

Others in Wales would disagree with that opinion. Dr Rebecca Rumbul of the Welsh Governance Centre describes the English majority in Westminster as "huge".

5. The 'neverendum'

One scenario following a "No" vote is that independence campaigners act on the saying, "If at first you don't secede, try and try again."

Both sides of the campaign have stressed the vote is a one-off. Better Together leader Alistair Darling warned "there is no going back" and the Scottish Deputy First Minister Nicola Sturgeon hailed it as "a once in a lifetime opportunity".

But several commentators have drawn comparisons between Scotland and Quebec, where there were two referendums within 15 years as part of repeated efforts to arrive at a constitutional settlement, sometimes referred to as the "neverendum".

A YouGov/Sun poll in August found a fairly mixed picture on support for another referendum in Scotland, with 25% backing another vote within the next 10 years and 17% within the next 30 years. Thirty-nine per cent believed there should not be another referendum at all.

Michael Keating, professor of Canadian and Scottish politics at Aberdeen University, doesn't see much appetite for a further referendum.

"A huge amount of time and energy has been expended on this campaign. People will want to get on with the business of renegotiating powers for Scotland."

The legacy of a "No" vote, he predicts, "will not be to kill off the campaign for independence - which will continue - but to put everything on the table in terms of rebuilding the constitution, to fire up debates on welfare, on pensions, on the economy, which were not being had before".

The only thing he does foresee prompting another plebiscite has to do with the possibility of another referendum altogether - on whether the UK should leave the EU.
