But pressed on whether she knew whether Sir Graham had received the 48 letters from Tory MPs needed to trigger a vote of no-confidence, she said: “I have regular conversations with Sir Graham Brady.
“Graham Brady will make it known…If 48 letters are reached, Graham Brady will make it known.”
Asked again if she knew, she said: “I have not…as far as I know no. The answer to your question is no.”
Mrs May revealed ‘as far as she knows’ she isn’t facing a leadership challenge from her own party.
She said she spoke to 1922 Committee chairman Sir Graham Brady, the only person who knows how much immediate trouble she’s in, “at the end of last week.”
Theresa May has warned warring Tory rebels that toppling her would risk delaying or stopping Brexit .
The Prime Minister said a change of leadership would only ‘breed uncertainty.’
She told Sky News’ Sophy Ridge: “A change of leadership at this time is not going to make the negotiations any easier and it is not going to change the parliamentary arithmetic.
“It will bring uncertainty and increase the risk that we delay the negotiations, and that is a risk that Brexit gets delayed or frustrated.”
Mrs May said that the next seven days “are going to be critical”, and said she would be travelling back to Brussels to talk to figures including Jean-Claude Juncker, the European Commission president.
She told Ridge: “I will be going back to Brussels.
“The negotiating teams are working as we speak and obviously which day I go back to Brussels… will partly be about how those negotiations go.
“I will be going back to Brussels, I will be in touch with other leaders as well, because the summit next week – and it is next week – this special European Council, will be among the European leaders.”
