The Metropolitan Police has announced it has concluded its investigation into lockdown-breaking parties in Downing Street and across Whitehall.

Fines have been issued for at least eight of the 12 events under investigation.

The names of most of the people fined over coronavirus restriction breaches have not been made public.

However, it was previously confirmed that Prime Minister Boris Johnson, his wife Carrie, and Chancellor Rishi Sunak were fined over a birthday bash in the Cabinet Room on June 19 2020.

The police identified the following events as breaching restrictions:

A leaked email from the Prime Minister’s principal private secretary Martin Reynolds showed No 10 staff were invited to “bring your own booze” to an event in the Downing Street garden.
