The Prime Minister's former aide Dominic Cummings says that Boris Johnson ‘lied to Parliament’ over a Downing Street party.
Mr Cummings has written on his blog that multiple witnesses 'would swear under oath' that Mr Johnson lied about the May 20, 2020 event.
The new revelations come after Mr Johnson told MPs he “believed implicitly” that the BYOB bash was a 'work event'.
