The acting head of the Metropolitan Police has been asked by London Mayor Sadiq Khan to explain the force’s decisions over partygate after pictures emerged of Boris Johnson drinking at a gathering for which he was not fined.

Mr Khan wrote to Sir Stephen House on Tuesday to seek answers about the Met’s decisions in individual cases in the Downing Street investigation.
