he was asked in parliament if there was a party on that day that these photos were taken. His response to being asked was there a party on that day was "no. and all rules were followed."
arguably then, he now has definitively lied to parliament.
Also, confusion reigns now, as others were at these parties, and have been fined but boris hasn't, and it beggars belief as to why. Hopefully he said he wasn't there on the police questionnaires and these photos are evidence of lying to the police also...
