Boris Johnson has been urged to recuse himself from picking Cressida Dick’s replacement as Met chief while he is under investigation over Partygate.

Dame Cressida dramatically announced she was standing down as Commissioner on Thursday evening after London Mayor Sadiq Khan made clear he had no confidence in her plans to reform the service.
