Johnson told MPs he did not realise 20 May 2020 event was social gathering but ex-aide says PM was advised not to allow it
Dominic Cummings has accused Boris Johnson of lying after No 10 denied the prime minister was warned against allowing a “bring your own booze” party during the first lockdown.
Johnson admitted to parliament last week that he attended drinks in the Downing Street garden on 20 May 2020 but claimed he had not realised it was a social gathering.
