MET Police boss Dame Cressida Dick is facing fury over possible delays to the Partygate report.
There are fresh doubts over whether Sue Gray’s document can be published while a police investigation is ongoing.
Top government legal advisers argue that her findings into alleged No10 lockdown breaches must be delayed until after the Met inquiry concludes.
And that could potentially be weeks away. Dame Cressida had planned to wait for the Cabinet Office report to be released before deciding whether to launch a probe.
But she performed a spectacular U-turn on Tuesday in the face of criticism.
External lawyers have told the Government they face an HR nightmare if Ms Gray’s report is released and she names people currently subject to a separate police investigation.
But that legal advice could still be overruled with a watered down version of the report being put out.
A Whitehall source said: “Anything worth reading will now have to be held back.
“So there comes a point in deciding if it is even worth publishing until it can be run in full.”
Another government figure admitted: “Cressida has completely f***ed it all up.”
Ms Gray is said to be still pushing for publication, with Downing Street chiefs insisting they want to see the findings.
Today Lord Frost, the one-time Brexit talks boss, writes in Trending In The News: “The future of Boris Johnson’s government needs to be settled in the next few days.”
And backbench Tory rebel ringleader Mark Harper claimed: “The report must be published in full.
“Any attempt to conceal or suppress crucial details would be wrong.”
Senior civil servants and political aides are expected to get a major dressing down from Ms Gray for their bad behaviour during lockdown.
Sources claim those close to the PM will be accused of putting him at huge risk and offering him duff advice.
The uproar comes as the Tory revolt against the PM continues to fizzle out — with MPs fearful they will get “rebel’s remorse” if they knife Mr Johnson.
Last night, Tory MP Connor Burns, who faced ridicule for saying Boris was “ambushed by cake” at an event in June 2020, added another twist to the tale.
He claimed in a podcast interview: “I’m told, under some authority, that there actually wasn’t a cake.”
