LONDON (AP) — Prime Minister Boris Johnson was braced for the conclusions of an investigation into allegations of lockdown-breaching parties, a document that could help him end weeks of scandal and discontent, or bring his time in office to an abrupt close.

Senior civil servant Sue Gray could turn in her report to the government as soon as Wednesday. Johnson has previously promised to publish it in full and to address Parliament about its findings.

“When I receive it, of course I will do exactly what I said,” Johnson said during a testy Prime Minister’s Questions session in the House of Commons.

He batted away questions about the scandal and his future, saying he had “absolutely no intention” of resigning.

Gray’s office wouldn’t comment on timing, and Foreign Secretary Liz Truss said the Conservative government hadn’t yet received the report Wednesday morning.

“I expect we won’t have much longer to wait,” she told the BBC.

Truss said she couldn’t guarantee the government would publish the full report, saying there could be “security issues that mean parts of it are problematic to publish. But we will absolutely publish the findings of the report.”

Allegations that the prime minister and his staff flouted restrictions imposed on the country to curb the spread of the coronavirus have caused public anger, led some Conservative lawmakers to call for Johnson’s resignation and triggered intense infighting inside the governing party.

Wednesday’s headlines provided more bad news for Johnson, whose popularity in opinion polls has plunged amid the scandal. The Guardian’s front-page headline spoke of “PM’s peril,” while the left-leaning Daily Mirror said bluntly: “Number’s up, PM.” The right-of-center Daily Mail differed, declaring Britain: “A nation that has lost all sense of proportion.”

Johnson has urged his critics to wait for Gray’s conclusions, but his “wait and see” defense weakened Tuesday when police said they had opened a criminal investigation into some of the gatherings.

London’s Metropolitan Police force said “a number of events” at Johnson’s Downing Street office and other government buildings met the force’s criteria for investigating the “most serious and flagrant” breaches of coronavirus rules.

Both the criminal and civil service investigations stem from claims that government staff held late-night soirees, boozy parties and “wine time Fridays” while Britain was under coronavirus restrictions in 2020 and 2021.

The “partygate” allegations have infuriated many in Britain, who were barred from meeting with friends and family for months in 2020 and 2021 to curb the spread of COVID-19. Tens of thousands of people were fined by police for breaking the rules.

If detectives quiz Johnson about his involvement, it will be the first time a prime minister has been interviewed by police since Tony Blair was quizzed as a witness over a “cash for honors” scandal in 2007. No one was charged in that case.

Conservative lawmaker Andrew Rosindell downplayed the extent of any wrongdoing by the prime minister.

“I’m sure there are ministers that get parking tickets and speed fines, too,” he said. “Lots of people break the law in small ways, sometimes unintentionally. He’s not robbed a bank.”

Johnson and his allies have tried, without much success, to calm a scandal that is consuming government energies that could be better spent confronting the international crisis over Russia’s military build-up near Ukraine and a far-from-finished coronavirus pandemic.

Johnson has apologized for attending one event, a “bring your own booze” gathering in the garden of his Downing Street offices in May 2020, but said he had considered the party a work gathering that fell within the rules.

Johnson’s supporters have also defended a June 2020 surprise birthday party for the prime minister inside Downing Street.

Loyal lawmaker Conor Burns said Johnson didn’t know about the gathering in advance.

“It was not a premeditated, organized party … He was, in a sense, ambushed with a cake,” Burns told Channel 4 News.
