Boris Johnson was warned against claiming all Covid guidance followed new Partygate evidence reveals

Former PM ‘allowed party culture to continue’, it has also emerged in bombshell evidence ahead of TV grilling

Britain’s most senior civil servant has said he did not give Boris Johnson any assurances that Covid rules were followed at all times in No 10 during lockdown.

Cabinet secretary Simon Case said he offered no assurances in written evidence given to the cross-party privileges committee due to grill Mr Johnson later on whether he misled MPs over the Partygate scandal.

It has also emerged that Mr Johnson was warned by his principle private secretary Martyn Reynolds against claiming that all Covid guidance had been followed – but went ahead and made a denial in the Commons.
