Boris Johnson is to quit as leader of the Tory Party after a swathe of ministerial resignations.
A leadership contest is now expected to begin although Mr Johnson is expected to remain as caretaker Prime Minister until the autumn.
He has still not commented publically about his resignation although he will address the nation today where he will officially announce he is standing down and why.
Mr Johnson is expected to make the announcement outside Number 10 Downing Street at lunchtime at around 12.30pm.

More than 50 MPs have resigned from government or party roles since Tuesday night, when the mass exodus was triggered by the resignations of Rishi Sunak and Sajid Javid from the Cabinet.
The Prime Minister had sought to defy his critics and carry on in office, despite warnings from Cabinet colleagues that this was not sustainable.
But resignations continued and Chancellor Nadhim Zahawi – who was only appointed to the role on Tuesday – went public with his call for the Prime Minister to quit.
The timetable for the Tory leadership contest will be agreed between the 1922 Committee, which runs the parliamentary proceedings to whittle the candidates down to two, and Conservative headquarters.
