“As politicians, we have a responsibility not to simply say what we want, but also to explain how we can achieve it,” she said.
“I recognise that you would want to put forward your own proposals and I would be happy to discuss them with you.
“You have always believed in the importance of dialogue in politics.
“Do you really believe that, as well as declining to meet for talks yourself, it is right to ask your MPs not to seek a solution with the government?”
Despite the letter, however, it is understood that several Labour MPs have been to Downing Street to meet the PM, including Yvette Cooper, Hilary Benn and John Mann.
Benn and Cooper both appealed to the PM to rule out no-deal.
When asked whether Corbyn should meet May, Benn, who is chair of the Commons’ Brexit committee, replied: “That is a decision for Jeremy to take.
“He’s demonstrating that it’s not just the Prime Minister who can be stubborn – there is a step she can take and Jeremy Corbyn is quite right to say to her, as all of us have, you must take no-deal off the table.”
