East MPs among Brexit vote rebels

A number of MPs in the east of England were among 11 Tory rebels who voted against the government, defeating a key Brexit vote.

The backbench revolt in the Commons last night resulted in the first significant defeat for Theresa May's Brexit legislation.

Eleven Conservatives - including South Cambridgeshire's Heidi Allen, Huntingdon's Jonathan Djanogly, Beaconsfield MP Dominic Grieve and North East Hertfordshire's Sir Oliver Heald - chose to side with Labour in demanding that MPs be given a vote on any Brexit deal before it is finalised.

Residents concern over Cambridge South station parking

People living near the proposed site of the new Cambridge South railway station say they are concerned it could be built without a car park.

It would be the third station in the city. The second, at Cambridge North, opened three months ago.

Since then, some residents near Cambridge North say initial fears that rail commuters would clog up their streets to avoid parking charges at the station, have become reality.

"Since the station's been open, I've seen a lot more cars parked on side roads. People living on those roads haven't had their usual spaces to park," said one local resident.

The MP for South Cambridgeshire, Heidi Allen, says it doesn't worry her that the station is being planned without a car park.

"Cambridge South will be a different kind of station," she said.

"The station is for the bio-medical campus and the hospital, it's a destination, not a transport route.

"People won't be using this station to access to rail network.

"This station could take some of the pressures off parking in the area, as people who work at and use the hospital will have an alternative mode of transport."

Heidi Allen 'angry' at DUP deal

Hannah Olsson

BBC Radio Cambridgeshire political reporter

The Conservative MP for South Cambridgeshire, Heidi Allen, has strongly criticised her party's deal with the DUP - as well as the party's general election campaign.

Speaking during a debate on the Queen's Speech in the House of Commons, Ms Allen said she could "barely put into words" her "anger" at the deal done with the DUP.

She said she wanted to put on record her "distaste for the use of public funds to garner political control" and warned that "never again" should a government prioritise spending in such a way.

She also warned that a backbencher's vote must be "earned" and is not "given unconditionally".

Ms Allen criticised the Conservative's general election campaign for failing to display empathy and compassion - and said it had demonstrated that the gap between people's lives, and the "decision makers", had grown too big.

She stressed that the party "must change" - and that it must "put people at the heart of everything we do".

"Financial and economic competence is not enough," she said.

"I want a Conservative party where people vote for us because they want to, not because they feel they have to."

Proposed DUP deal 'makes me feel uncomfortable', says South Cambridgeshire MP

Adam Jinkerson

BBC Local Live

The Conservative MP for South Cambridgeshire has called for Parliament to work across the political spectrum on the "big items", as she continues to vent her dissatisfaction at a potential Tory deal with the Democratic Unionist Party (DUP).

Heidi Allen tweeted this on Saturday...

Theresa May is due to meet the DUP leader, Arlene Foster, at Downing Street today, to try and form a minority Tory administration with backing on key votes from the unionists. Mrs Foster has described it as a "tremendous opportunity" for her 10 MPs following a hung parliament.

Speaking to BBC Radio Cambridgeshire this morning, Ms Allen said the general election "has massively backfired".

"It's a mess. I can't pretend it isn't. It's gone badly wrong. The campaign backfired on us and this has to be our wake-up call," she said.

"There are so many reasons [a deal with the DUP] makes me feel uncomfortable. Not just on the civil liberties issue. Historically how they've spoken about changing the abortion time limit, rights for LGBTI people. Just very different to our more liberated views in this country.

"I'd rather it was a minority government.

"Now is the time we need to try and work cross-party. It doesn't matter what party you are from. We should work together on the big items.

"I don't think it's 100% certain that [Theresa May] will be able to come through this at all, but I did see a woman last night at a meeting of backbenchers who was certainly prepared to be humble to apologise and say, 'let me try'."

South Cambridgeshire MP 'proud'

Ms Allen won with 33,631 votes.

However, Labour added almost 10% to their share compared with the 2015 vote and Ms Allen's majority was cut by nearly 5,000.

After the results were announced, she said that she expected "a threat from the Liberal Democrats, but Labour have done very well".

Don't second guess the electorate

Hannah Olsson

BBC Radio Cambridgeshire political reporter

What a night!

You'd think we'd have learned over the last couple of years not to second guess the electorate, but there won't be many people in Cambridgeshire who would have predicted this morning Labour would have won Peterborough and had a huge swing in Cambridge.

We knew Peterborough was in Labour's sights, but few really believed that Conservative Stewart Jackson would end his 12-year stint as the city's MP. But Labour's Fiona Onasanya was the one to unseat him - with a tight majority of just 607.

Meanwhile, everyone I spoke to predicted another close fight between Labour and the Liberal Democrats in Cambridge, but in the end it was far from it. Daniel Zeichner won convincingly with a majority of 12,661 over Julian Huppert.

Elsewhere, Cambridgeshire's other Conservative MPs have kept their seats, some increasing their majorities.

But also we've seen a surge in support for Labour in their seats and the bottom fall out of the UKIP vote.
