Gordon Brown says there WILL be a second Brexit referendum.

The former prime minister made the comments to The Institute for Government in a speech on Monday.

Mr Brown, who served as Prime Minister until 2010, said he believes a second referendum on Britain's EU membership is inevitable.

He said since 2016 the situation has "changed".

Mr Brown added: "At some point they will want to have the final say."

“No reason we can’t go back to Brussels, it is possible to re-negotiate,” Brown added.

A majority of voters in all 259 Labour-held seats across Britain now back the idea of a referendum on the outcome of Brexit negotiations, according to a vast new survey.

That includes every Labour-held seat in Birmingham.

And a majority of Labour supporters in every Labour-held seat in the country not only want a "People’s Vote" - but would opt to stay in the EU if they were given the chance.

The findings will put further pressure on Labour leader Jeremy Corbyn to support another referendum on Brexit. Supporters of another poll call it a People's Vote.

Labour is currently committed to keeping the option of another referendum "on the table" if the Government fails to secure an acceptable Brexit deal with the EU, and if there is no general election before Brexit.

Data scientists working for polling company YouGov used techniques that proved far more accurate than conventional polling in helping them predict the outcome of last year’s General Election. The analysis, based on the biggest poll of 26,000 voters, shows that when people who said they did not know or would not vote are excluded:

  • Voters from across the political spectrum in all 259 Labour-held seats want a People’s Vote, with the percentage varying from 70% in Birmingham Hall Green and Birmingham Ladywood to 59% in Birmingham Erdington.
  • Labour voters in all Labour-held seats want a People’s Vote by an even bigger margin - with a majority of at least two thirds being recorded in every constituency the party currently holds
  • The constituency where Labour voters back a People’s Vote by the biggest margin is Islington North, the seat of the party leader, Jeremy Corbyn where a total of 80% of the party’s supporters back the idea of giving the public the final say on Brexit.

Birmingham voters who support a second referendum on Brexit:

BIRMINGHAM EDGBASTON 60%
BIRMINGHAM ERDINGTON 59%
BIRMINGHAM HALL GREEN 70%
BIRMINGHAM HODGE HILL 67%
BIRMINGHAM LADYWOOD 70%
BIRMINGHAM NORTHFIELD 56%
BIRMINGHAM PERRY BARR 63%
BIRMINGHAM SELLY OAK 63%
BIRMINGHAM YARDLEY 63%

The figures show the proportion of voters - whichever party they support - who back a "People's Vote" on the Brexit deal, after people who said "don't know" are excluded.

Sutton Coldfield is not included because polling company YouGov only looked at seats with Labour MPs.

Jess Phillips, the Labour MP for Birmingham Yardley, today declared her support for the People’s Vote campaign.

She said: "It's no surprise to me that my constituents feel that they have been failed in the negotiations and are changing their mind on Brexit. They hear posh blokes on the telly telling them what's good for them and they realise that this miserable plan was never about them.

"One thing is for sure: I trust my constituents to make a call on what's best for them and Britain - much more so than the politicians in charge of it. And my constituents back a People’s Vote and having seen the mess the government have made of Brexit would now choose to remain in the EU.”

"People want to make out they are thick or basic or they can't take a bit of debate, that's all rubbish. If I had to pick who decided my fate between Theresa May or the people in my community I'd pick them every single time. And that’s why I’m backing the People’s Vote campaign."

Her seat in Birmingham Yardley voted to leave by a margin of 60% to 40% two years ago.

But Labour voters split 56% to 44% in favour of staying in the EU and this margin has now increased to 61% in favour of remain to 39%.

Overall, her constituency Is now in favour of a People’s Vote by a margin of 63% to 37% - but Labour supporters are significantly more positive with 73% in favour and just 27% against.

Pat McFadden, the Labour MP for Wolverhampton South East, said the findings of the survey would help him make up his mind on how to vote in the weeks to come, adding: “I have had doubts about the idea of a fresh vote on this issue, not least because I know how my constituency voted two years ago and the strong feelings and divisions that referendum aroused.

"But a lot of new information has come to light since then - including the huge divorce bill what wasn't mentioned at the time, the problems over the Northern Ireland border that were casually dismissed by Brexiteers during the referendum and the difficulty of securing an even half-decent-deal.

“All of this means the Brexit we may get is a million miles from the one that was promised. This enormous survey by the People’s Vote campaign showing there is an overall majority in my seat in favour of the public having the final say – and that almost three-quarters of Labour voters back the idea - is important for MPs like me.

"I will keep listening to voters on this issue because this is such a huge issue for the country and it’s vital that the people’s voice is heard.”

Overall, his Wolverhampton SE seat would still back Brexit by a margin of 57% to 43% in a fresh public poll, but the figures are reversed for Labour voters who would opt to stay in the EU by a margin of 57% to 43%.

Peter Kellner, a former President of YouGov and one of Britain’s most respected pollsters, said: "This research uses a technique known as Multilevel Regression and Post-stratification, or MRP for short. It enables us to estimate the views of people in particular areas – in this case parliamentary constituencies – by analysing data from a larger area, such as a region or nation.

"The key to this is to have enough data on enough people. For analysing attitudes to Brexit and a People’s Vote, YouGov questioned more than 25,000 people across Britain."

He added: “MRP results have twice confounded the sceptics. In last year’s general election, the model not only indicated a hung Parliament, when most surveys showed the Conservatives heading for a comfortable victory; it also showed that the Tories were in danger in two of their iconic strongholds, Kensington and Canterbury."
