Sue Gray has received photos of Downing Street parties which include Boris Johnson and others close together with wine bottles, Sky News understands.
The latest revelation comes shortly after a government source said senior civil servant Ms Gray’s report into parties in Downing Street and Whitehall that may have broken COVID rules could be published as soon as tomorrow.
Earlier on Tuesday, Metropolitan Police Commissioner Dame Cressida Dick announced that the force was investigating “a number of events” for potential breaches of COVID-19 regulations.
Sky News understands the Met has not raised an objection to the Cabinet Office inquiry being released before its criminal investigation has concluded.
Downing Street reiterated on Tuesday afternoon that the government wants the report to be published “as soon as possible” and insisted Number 10 is not trying to block its publication.
The prime minister’s official spokesperson told reporters talks are taking place between Ms Gray’s inquiry team and the Metropolitan Police to decide what can be published from her investigation into the ‘partygate’ row.
It is understood Number 10 has yet to receive a copy of the report.
