UK Prime Minister Boris Johnson is to face a vote of no confidence later today after the threshold of 54 letters from Conservative MPs seeking his departure was reached.
In a statement, the chairman of the 1922 committee that represents backbench Tories, Graham Brady, said the threshold of 15 per cent of MPs seeking a confidence vote has been exceeded.
To stay in office, Mr. Johnson needs to win the support of at least 50 per cent of all Tory MPs plus one, totalling 180.
If he wins he is theoretically safe from such a challenge for a year – although the rules can be changed.
Mr. Johnson is due to address backbench MPs to try to rally support.
