Partygate inquiry homes in on Abba evening at Boris Johnson’s flat

Witnesses tell of lockdown gathering with alcohol, food and loud music at private apartment above 11 Downing Street

The inquiry into whether Boris Johnson misled MPs over rule-breaking parties in Downing Street is homing in on a gathering in his private flat, the Observer understands.

Follow-up exchanges with witnesses working with the inquiry are now taking place as the privileges committee, led by Labour grandee Harriet Harman, works its way through a huge tranche of evidence handed to it by the government at the end of last year.
