Boris Johnson, his wife Carrie former chief adviser Dominic Cummings and Mr Johnson’s principal private secretary Martin Reynolds were all pictured, in a photograph leaked to The Guardian, sitting around a table in the No 10 garden, with wine and cheese in front of them.
Some 15 other people were also in the photograph, but the Prime Minister has insisted this was a work meeting, saying: “Those were meetings of people at work, talking about work.”

According to sources cited by The Mirror, the fridge became necessary for staff’s “wine-time Fridays” which were held through lockdown, with the Prime Minister allegedly encouraging the parties to help aides “let off steam”.
The regular social gatherings were reported to be particularly popular among staff between autumn 2020 and spring 2020 when staff were “fatigued” with tough Covid restrictions which banned socialising.
Mr Johnson was said to have attended a “handful” of these gatherings.
– December 14 2020: Party featuring Tory London mayoral candidate Shaun Bailey and staff

He quit his role chairing the London Assembly’s police and crime committee after The Mirror published a picture showing him at the gathering.

– December 16 2020: Department for Transport party
The Mirror reported senior civil servants were “boozing and dancing” at the event, allegedly planned by staff from Transport Secretary Grant Shapps’ office.
A DfT spokesman said: “Fewer than a dozen staff who were working in the office had a low-key, socially distanced gathering in the large open-plan office after work on December 16, where food and drink was consumed.
“We recognise this was inappropriate and apologise for the error of judgment.”
