A cut-back version of Sue Gray's long-awaited report is due to be sent to Downing Street "shortly" following lengthy talks with the Met Police, reports say.
It is understood that the report is to be sent to Number 10 Downing Street in the coming hours or days after Ms Gray gave the Met Police evidence of possible lockdown breaches.
It will then be for Number 10 to decide when to publish it, with the government having previously suggested that that would happen when Parliament is sitting - which is next on Monday.

However, after an intervention by the Met Police, only "minimal reference" to Downing Street parties that the force is investigating will be included.
It is unknown if or when a more complete report with all the details will be published following the conclusion of the Met Police investigation.
The Met Police asked Sue Gray to only include "minimal references" to the parties that the force is investigating in order to avoid prejudicing its enquiry, The Mirror reports.
Scotland Yard is examining "a number of events" in Downing Street and Whitehall while the country was under Covid restrictions - but has not publicly said which ones.
Reports suggest that it could be as many as eight gatherings.
The Sue Gray report had been expected to be published in full this week, but the timing was through into chaos by Cressida Dick's bombshell announcement of a police investigation on Tuesday.
It is understood that the Whitehall inquiry is ongoing, but Ms Gray may be forced to decide whether to delay her report or remove key details.

Opposition MPs slammed the appearance of an "establishment stitch-up" and a "Whitehall whitewash" that could see Boris Johnson given a reprieve.
Marvin Rees, the Labour Mayor of Bristol, said tonight that Boris Johnson's previous apology "won't be enough", but he may last in office "until we are all so tired of talking about it that we give up".
He also said that the public's "ability and willingness" to believe that politicians have their best interests at heart would suffer if the prime minister stays in office.
Boris Johnson will be spending the weekend at Chequers, the prime minister's country retreat, as he attempts to stabilise his battered leadership.
In a statement on Friday, Scotland Yard said: "For the events the Met is investigating, we asked for minimal reference to be made in the Cabinet Office report.
"The Met did not ask for any limitations on other events in the report, or for the report to be delayed, but we have had ongoing contact with the Cabinet Office, including on the content of the report, to avoid any prejudice to our investigation."
However, some legal figures questioned have why publishing the Whitehall report would prejudice the police investigation.
