Downing Street has yet to receive a report into lockdown parties in Downing Street and across Whitehall, the foreign secretary has confirmed to Sky News.

Speaking to Kay Burley, Liz Truss said the government would release the “findings” from the Cabinet Office inquiry, which is being led by senior civil servant Sue Gray.

There have been calls for Number 10 to release the document in full.

However, the foreign secretary said there could be “security issues” which mean parts of it are “problematic to publish”.

“But we will absolutely publish the findings of the report,” she pledged.

Ms Truss also said Boris Johnson has her “100% support” as the prime minister faces calls, including from some of his Conservative MPs, to resign over the partygate revelations.

The crisis engulfing the PM deepened on Tuesday when the Metropolitan Police announced it is investigating a “number of events” in Downing Street and across Whitehall for potential breaches of COVID-19 regulations.

Expectations had been raised that Mr Johnson would address the Gray report’s findings in the Commons this lunchtime.

On Tuesday afternoon, it was understood that Number 10 would publish the report compiled around midday today and then the PM would make a statement in the Commons after PMQs.

But it is now believed the document will not be released for publication until later this afternoon at the earliest, with the chances of this being delayed until Thursday growing.

Uncertainty has been cast over its publication as Ms Gray’s team hold discussions with the Met.
