Johnson, who in 2019 won his party's biggest majority in more than 30 years on a pledge to "Get Brexit Done", has repeatedly apologised for the parties and said that he was unaware of many of them.

However, he attended what he said he thought was a work event on May 20, 2020 which revellers had been told to "bring their own booze".

Asked directly in the House of Commons if he would resign on Wednesday (January 19), Johnson said: "No".
