Boris Johnson is facing a possible police interview over lockdown breaches in Downing Street as the Metropolitan police said they intended to start questioning witnesses after sending out questionnaires to more than 100 people.

But the police statement – issued two months since inquiries began – suggests officers have not yet found breaches that meet the evidentiary threshold for fixed-penalty notices to be issued without further interviews. No FPNs have been issued so far, the force said.
