This week’s Prime Minister’s Questions saw Boris Johnson apologise for the party held at Number 10 during lockdown in May 2020.

       Mr Johnson has already confirmed that Sue Gray, the second permanent secretary in the Cabinet Office, has been tasked with not only investigating this party, but all government parties that took place during coronavirus restrictions.

       There are currently thought to be 12 parties that took place in Number 10 or government departments between May and December, with some coming hours after new restrictions came into force.

       The Prime Minister announced the first “careful steps” out of lockdown, but social distancing must still be obeyed. He added that fines would be increased for those found to break them.

       Restrictions meant that people could not leave their home without a reasonable excuse, and meet only one person outside while exercising.

       December 10: Department for Education Christmas party

       The Department for Education confirmed that the event, which saw two dozen people drinking in the department canteen, took place.

       Susan Acland-Hood, a senior civil servant, said that it had been done at the request of Gavin Williamson, the education secretary at the time, who wanted to thank staff for their hard work.

       She said that she had asked Simon Case, the cabinet secretary, to investigate the gathering.

       In late December 2021, Mr Case, the country’s top civil servant, was forced to step down from his task of investigating alleged parties after it emerged that he had attended an impromptu drinks gathering in mid-December 2020.

       It was reported that as many as 20 staff shared drinks in his Whitehall Office.

       December 15: Christmas quiz

       A picture emerged of the Prime Minister hosting an online quiz in mid-December whilst in Downing Street, alongside two members of his team wearing tinsel and a Santa hat.

       About a dozen of Grant Shapps’s staff were accused of “boozing and dancing”, for which the Department for Transport apologised.

       This came on the same day that London had moved to the highest tier of restrictions at the time - Tier 3.

       December 17: Second Cabinet Office party

       The Cabinet Office confirmed that staff took part in a virtual quiz, which was reportedly listed in digital calendars as “Christmas party!” in Simon Case’s office.

       December 18: No. 10 Christmas party organised by Martin Reynolds

       It is believed that about 40 of the Prime Minister’s top team were reported to have held a Christmas party featuring secret Santa gifts.

       The next day, the Queen attended a socially-distanced funeral for the Duke of Edinburgh in Windsor.
