Theresa May faced down her Brexiteer critics on Sunday, warning them that ousting her could risk the UK not leaving the EU in March 2019.



The prime minister revealed she would be going back to Brussels this week to thrash out details of the future relationship with the EU, but defended her divorce deal and signalled that cabinet Brexiteers attempting to secure changes would be disappointed.



"A change of leadership at this point isn't going to make the negotiations any easier, and it's not going to change the parliamentary arithmetic," May told Sky News' Sophy Ridge. "What it will do is mean there is a risk that actually we delay the negotiations, and that's a risk that Brexit gets delayed or frustrated."

Asked whether she knew if the threshold of 48 letters required to trigger a no-confidence vote in her leadership had been reached, the PM replied: "As far as I know, no it has not".
