A Downing Street spokesperson has said Boris Johnson "welcomes" Monday's confidence vote in his leadership.
“Tonight is a chance to end months of speculation and allow the government to draw a line and move on, delivering on the people’s priorities," the spokesperson said.
"The PM welcomes the opportunity to make his case to MPs and will remind them that when they’re united and focused on the issues that matter to voters there is no more formidable political force.”
Dozens of MPs have publicly expressed their dissatisfaction with Johnson's recent performance. If Johnson fails in making his pitch on Monday, he'll have to step down.
