A BBC Question Time audience member ripped into the panel warning about the consequences of Brexit not being delivered.
The audience member claimed that if Brexit was not delivered it could lead to the rise of a political figure similar to that of US President Donald Trump.
He said: “If we get to a position where this referendum from two years ago is overturned, and there is no Brexit, then we will have Donald Trump.
“Be careful of what you hope for over here.
“Be careful of trying to unwind that referendum. Because there are 17.4million people will be very annoyed.
“Down the line, we will get consequences of that which we will not want, it might be Donald Trump, it might be worse. But, be careful what you wish for.”
Labour’s shadow home secretary Diane Abbott added to the audience member’s concerns about a second referendum.
Ms Abbott said: “I will say this about the second referendum, which a lot of people are talking about: You should be careful what you wish for.
“Because my suspicion is, if we had a second referendum now the same people who voted leave last time, who are not largely speaking in London, would vote to leave again saying: ‘Didn’t you hear us the first time?’”
However, she dismissed host David Dimbleby’s suggestion this means her party should rally around Theresa May and whatever her Brexit deal will be.
She said: “Not if it’s not good for the country.
“How could any politician live with themselves if they genuinely thought it was a bad and destructive deal, which would damage manufacturing, which would damage education institutions?
“We haven’t even agreed on the security aspect of it yet – if we will have access to EU databases after we leave!”
Last month an estimated 700,000 people marched in London to demand another say on leaving the Brussels bloc.
Prime Minister Theresa May has repeatedly ruled out having another referendum on leaving the European Union.
The Labour Party have said they would prefer a general election over a second referendum, but leading frontbenchers have added that all options remain “on the table”, should the Prime Minister’s Brexit deal get voted down in the House of Commons.
