Cross-party Brexit talks have collapsed after Jeremy Corbyn told Theresa May they had “gone as far as they can”.
The Labour leader told the Prime Minister “we have been unable to bridge important policy gaps between us”.
Mr Corbyn also said the prospect of a change in Tory leadership meant the Government was becoming “ever more unstable and its authority eroded” and Labour could not be confident in any cross-party agreement being delivered.
Mrs May will set out the timetable for her departure in early June after a crucial Commons vote on the Withdrawal Agreement Bill.
In a letter to Mrs May, Mr Corbyn said: “I believe the talks between us about finding a compromise agreement on leaving the European Union have now gone as far as they can.”
He added: “While there are some areas where compromise has been possible, we have been unable to bridge important policy gaps between us.
“Even more crucially, the increasing weakness and instability of your government means there cannot be confidence in securing whatever might be agreed between us.”
