Jeremy Corbyn has been urged to join forces with other opposition leaders to push for a new Brexit referendum.
The leader of the Liberal Democrats, Sir Vince Cable, and the Westminster heads of the SNP and Plaid Cymru, Ian Blackford and Liz Saville Roberts, have written to Corbyn, inviting him to a joint meeting.
The move follows Labour’s shift in favour of backing a new referendum on Brexit.
Cable said: ‘Opposition leaders have been meeting for several months working together to secure a People’s Vote.
‘Now that Labour has decided to support giving people the final say, Jeremy Corbyn should join us, so we can work together and stop Brexit.
‘I hope Jeremy Corbyn doesn’t waste any more time. He must do the right thing and join the Liberal Democrats in offering the people an exit from this Tory mess.’
Saville Roberts said: ‘Labour have a face for all occasions, but now they’ve run out of masks.
‘Jeremy Corbyn must now follow his own policy and back a People’s Vote or face being the midwife of Brexit.
‘Opposition MPs have worked together for months. Our door has always been open to the Labour leader, but so far he has refused.
‘No more delays, no more excuses – Labour must work with other opposition parties to deliver a People’s Vote and a way out of this Brexit mess.’
