Attendees of the alleged lockdown-breaking parties at Downing Street and the Cabinet Office are reportedly braced for initial fines from the Metropolitan Police.
The Guardian suggested fixed penalty notices would be issued "imminently," while other outlets have reported they are due to surface soon. The police are investigating 12 events including as many as six Boris Johnson is said to have attended.
It emerged last week detectives investigating alleged parties had begun interviewing key witnesses. The Met said more than 100 questionnaires had been sent out to people at the reported gatherings.
