Ben Bradley Mansfield MP has submitted a letter of no confidence in Theresa May the Prime Minister after the Brexit withdrawal agreement was announced.
Mr Bradley is not alone in this as 20 Conservative MPs are believed to have done the same.
The Prime Minister released the withdrawal agreement which sets the terms of Brexit on Wednesday, November 14.
Mrs May has defended her Brexit deal saying it is in the 'public interest'.
Mr Bradley told your Chad before he submitted the letter that the current deal is “simply not acceptable".
Forty eight letters are needed to trigger a vote of no confidence in Mrs May.
Sources claim to the Express that the 1922 committee have received the 48 letters they need to trigger a leadership challenge.
Jacob Rees-Mogg, Lee Rowley and Nadine Dorries have also reportedly submitted letters.
Mr Bradley has been contacted for comment.
