Theresa May is expected to address the country in a statement outside Downing Street according to reports. 

It comes after enough Tory MPs have requested a vote of no confidence in Theresa May to trigger a leadership contest. 

The triggering of the vote comes after Mrs May dramatically put on hold the crunch Commons vote on her Brexit deal after admitting she was heading for a heavy defeat.

The Prime Minister is expected to give a speech to the 1922 committee at 5pm before a vote. 

The threshold of 48 letters - 15% of the parliamentary party - needed to trigger a vote has been reached and a ballot will be held between 6pm and 8pm on Wednesday evening in the House of Commons.
