Boris Johnson's own MPs are taking part in a confidence vote for him.
Conservative MPs are locked in their caucus room after 54 disgruntled members of his own party submitted letters calling for him to go.
Those letters were sent to Sir Graham Brady, the chairman of 1922 Committee which represents the MPs.
Earlier today, the Deputy Prime Minister Dominic Raab acknowledged the party's share of "distractions", but is still backing Mr Johnson.
UK correspondent Olly Barratt spoke to Susie Ferguson.
