Talks between Jeremy Corbyn and Theresa May aimed at breaking the Brexit deadlock have collapsed without an agreement.

Conservative whips had reportedly given up hope of reaching an agreement with Labour, while Mr Corbyn and the shadow cabinet had concerns about the durability of any deal due to Ms May's weak position.

But speaking on Friday, the prime minister blamed Labour division s over whether to demand a Final Say referendum for the failure of the talks.

As Ms May finally hit the campaign trail for the European elections - with just six days to go - she said: "In particular, we haven’t been able to overcome the fact that there isn’t a common position in Labour about whether they want to deliver Brexit, or hold a second referendum which could reverse it.”

But a Labour source hit back, pointing out Brexiteer cabinet ministers had also voiced “strident” opposition to a customs union, saying: “Ultimately, this is a prime minister that can’t govern and can’t deliver.”

Earlier, Mr Corbyn said: "We have been unable to bridge important policy gaps between us.”

It comes after the ex-foreign secretary Boris Johnson declared his intention to replace Theresa May after she bowed to pressure to quit in the summer months and make way for a new Tory leader.
