Staff at Number 10 reportedly held an indoor birthday party for the Prime Minister back in June 2020, when the country was at the peak of the pandemic.
According to a report from ITV News, the party was attended by around 30 people including Johnson’s wife Carrie Johnson and interior designer Lulu Lytle.
On June 10, just over a week before the alleged birthday bash, Boris Johnson had urged people to follow the government's Covid rules.
He said: "I urge everyone to continue to show restraint and respect the rules which are designed to keep us all safe."
Here's a full list of the Covid rules at the time the Downing Street birthday party reportedly took place.
Ban on indoor socialising
In June 2020, indoor social gatherings of two or more people were banned in England. People were only allowed to meet outside in groups of up to six, with the two-metre social distancing rule in place.
These rules on indoor socialising was not lifted until July 4, and even then it was limited to only two households.
People could share food outdoors only if they maintained social distancing, and anyone who stayed overnight away from home needed to have a "reasonable excuse" to do so.
Both in England and Northern Ireland, those living alone were allowed to form a "support bubble" to link them up with another household.
In Scotland, by June 19 2020, people were allowed to meet up with two households outdoors, but the risk of indoor socialising was still considered too great.
Covid rules for businesses
All pubs restaurants and social clubs were closed in England, as were museums, cinemas, galleries and libraries. None of these establishments reopened until July 4, when restrictions were loosened.
Outdoor gyms, playgrounds, theme parks, places of worship and community centres were also shut. All non-essential shops had been reopened just four days before the alleged party.
While football games in England were being allowed with empty stadiums in June, weddings with up to 30 guests were permitted only from July 4.
Schools shut under Covid rules
Secondary schools remained closed, with most pupils still attending classes online and only kids of key workers and vulnerable children going into schools.
Primary schools had reopened at the start of June 2020, including nursery, reception, year 1 and year 6 children, but many still remained studying from home.
Though then-Education Secretary Gavin Williamson spoke on June 19 about getting children back into the classroom, schools in England reopened fully only in September 2020.
