Labour leader Jeremy Corbyn has been blasted by Remainers in and outside of his party for stating he would back Brexit if he came into power.
Mr Corbyn, in an interview with the Guardian, said he would urge Labour to back leaving the EU bloc if it won a snap election.
As he did so, he criticised the European Union’s rules on state aid and competition, while stating he would go back and renegotiate a new Brexit deal.
Following this, Labour's former shadow business minister Chuka Umunna said the interview was "deeply depressing and disappointing".
In a Facebook post, he said: "Brexit is essentially a project of the hard right of British politics who want to turn Britain into a lightly regulated, offshore tax haven for the super rich, devoid of proper protections for workers, and one which seeks to dump the blame for the UK's problems on immigrants.
"Labour should stop pretending there is 'good' Brexit deal and we should certainly not be sponsoring this project because Brexit is the problem - it solves nothing."
While Ilford North Labour MP Wes Streeting, a critic of Mr Corbyn, also hit out at the statements.
He said: "Why peddle this myth that Labour would be able to renegotiate a Brexit deal at this 11th hour?
"How would Labour's Brexit be any better than remaining in the EU?
"Our members and voters are overwhelmingly pro-European. This lets them, and our country, down."
Mr Corbyn told the Guardian, when asked about a second referendum, he would suggest to “go forward” with leaving the Union.
He said: "It would be a matter for the party to decide what the policy would be; but my proposal at this moment is that we go forward, trying to get a customs union with the EU in which we would be able to be proper trading partners."
Labour passed a motion at its party conference in Liverpool in September it would seek a general election as its first choice, but left open the option of supporting a second referendum.
Mr Corbyn and other opposition frontbenchers have previously claimed that if Labour replaced Mrs May's Government by some means, they would be able to go back to Brussels to renegotiate her deal.
The SNP also attacked Mr Corbyn, as Westminster leader Ian Blackford called him "the midwife to the delivery of the Tory's Brexit plans".
Mr Blackford said: "Jeremy Corbyn has finally come off the fence he's been sat on for the past two years.
"But unfathomably he's come down on the same side as Theresa May.
"The Labour party is incapable of providing opposition to the worst UK government that most people can remember."
Lib Dem leader Vince Cable added Mr Corbyn "refuses once again to take the blinkers off".
He said: "He is ignoring the concerns of his own supporters and the economic damage experts warn Brexit will do to the UK economy.
"On Brexit, you simply cannot put a cigarette paper between Theresa May and Jeremy Corbyn."
