On 25 May Sue Gray’s report on the behaviour of' Downing Street staff during lockdown was published. The senior civil servant, who described how staff partied while the rest of the country was in lockdown, said many events 'should not have been allowed', and that the PM and his officials 'must bear responsibility for this culture'. Warnings about parties breaking Covid rules were ignored, the report says. Boris Johnson told MPs he took 'full responsibility for everything that took place on my watch'. He said he had been 'humbled by the whole experience' and had learned lessons.' Sue Gray said she learned of multiple examples of 'unacceptable' treatment of security and cleaning staff during her partygate investigation. Mr Johnson’s remarks are also being scrutinised by the Commons privileges committee, which must decide whether he knowingly misled Parliament, particularly when he categorically denied knowledge of rule-breaking parties. If he is found to have knowingly misled parliament, he would be in breach of the ministerial code and would in theory be expected to resign.
