Jeremy Corbyn has called on the next Tory leader to hold another referendum before October 31, adding that Labour would back remain.
In a BBC interview on Tuesday, the Labour leader said he would ‘make a case’ to parliament in September to get another public vote.
Meanwhile he affirmed his party would do ‘everything’ it can to take no deal off the table or allow a Tory deal.
Corbyn has been under pressure to shift to an anti-Brexit stance in recent weeks, including from shadow Chancellor John McDonnell and Deputy Leader Tom Watson.
He has not yet declared Labour’s policy in the event of a general election.
But in an email to party members on Tuesday, he said that if a referendum was called on the Brexit deal negotiated by the incoming Conservative prime minister, his party would support remain.
Corbyn wrote: “Whoever becomes the new prime minister should have the confidence to put their deal, or no deal, back to the people in a public vote.
“In those circumstances, I want to make it clear that Labour would campaign for remain against either no deal or a Tory deal that does not protect the economy and jobs.”
