The much-anticipated inquiry into Downing Street parties could be handed to Boris Johnson as soon as this weekend.
The Guardian reports that government sources say a redacted version of the document was sent to No 10 on Friday night.
The report, headed by senior civil servant Sue Gray, was initially expected to be released earlier this week.
But on Tuesday the Metropolitan Police launched a criminal probe into the events, asking that Gray remove any of the incidents they are investigating from the report.

Scotland Yard have faced widespread outrage over the request, with Labour, the Liberal Democrats and several Conservative MPs calling for the document to be released in full.
Labour Party leader Keir Starmer tweeted: “I want to see the Gray report in full.
“Our country faces huge challenges and it’s offensive that the Government’s sole focus is on cleaning up after themselves.
“Britain deserves better. The Prime Minister is unfit for office and must resign.”
The Met have defended their actions, telling The Guardian they are protecting “the integrity of the police investigation” in order to be “as fair as possible to those who are subject to it”.
Recent allegations against the Prime Minister include several breaches of lockdown regulations, including a reported birthday gathering in June 2020 to celebrate his 56th birthday.
He insists that he did not break Covid regulations at any point.
Sir Christopher Chope, the Conservative MP for Christchurch, called the Met’s actions an ‘abuse of power’.
Speaking on BBC Radio 4’s Today programme, he said: ““I don’t think it’s any of their business.
"This is a Cabinet Office inquiry and the findings have been concluded, and they’ve been shared – I don’t know why – with the Metropolitan police.
"Now the Metropolitan police seem to be interfering both in the content of the report and trying to prevent it being published in an unredacted form.”
He added that no criminal charges are imminent, meaning the issue can be freely discussed in the Commons.
The Prime Minister has previously promised that he will release the report to the public in full in order to be as transparent as possible.
