A group of MPs elected in 2019 - dubbed the "pork pie plotters - reportedly met this week to discuss ousting Boris Johnson after losing patience with the Prime Minister over the Downing Street party saga.
Mr Johnson is fighting for survival after a torrid few weeks, with a string of Tories publicly calling for him to quit.
