Boris Johnson pictured hosting No 10 Christmas quiz last year

Boris Johnson is facing further questions over whether he breached Covid laws after pictures emerged of him hosting a Christmas quiz in Downing Street while London was under tier 2 restrictions.

The prime minister was pictured on a screen reading out questions while staff were sat behind computers and conferred on the answers, the Mirror reported.

London was then under restrictions banning any social mixing between households.

A source told the newspaper that in one office there were four teams, each comprising six people.

Dozens of staff are understood to have signed up to participate in the quiz online but at 6.30pm that day many decided to take part from No 10 instead.

The quiz took place on 15 December, three days before an alleged Christmas party at Downing Street which is currently being investigated by the cabinet secretary, Simon Case.

On the day that Cummings dramatically left his job in Downing Street in November last year, blaring music and aides chatting were heard in the No 11 residence where Johnson lives with his wife, Carrie, sources have said.
