Partygate report reveals which events are under police probe - and three gatherings we'd never heard of

• Sue Gray's report has revealed three new parties held to mark the departure of No 10 staff.
• Including these unknown events, the police investigation comprises 12 events.

Three further lockdown-breaching gatherings have been uncovered by Sue Gray's inquiry into Westminster parties held during pandemic restrictions, all three of which are now the subject of a police investigation.

A party, reportedly held in the Downing Street flat by Boris Johnson's wife Carrie and friends to celebrate the departure of Dominic Cummings, is also included in the police probe.

An update into Gray's investigation, published Monday afternoon, revealed the following three gatherings previously not reported by the media:

• 18 June 2020: a gathering in the Cabinet Office on the departure of a No 10 private secretary
• 17 December 2020: a gathering in No 10 Downing Street on the departure of a No 10 official
• 14 January 2021: a gathering in No 10 Downing Street on the departure of two No 10 private secretaries

The identity of the individuals for whom the parties were held to mark their departure is not known, nor has Gray published the details of attendees or further information on the nature of the gatherings.

However all three gatherings are now under investigation by the Metropolitan Police following information provided by Gray's investigation team.
