But what will the investigation look at and when will the report be published?

Here’s everything you need to know.

What is the inquiry?

Sue Gray, a senior civil servant, has been tasked with investigating alleged breaches of lockdown rules within the Government.

Ministers have been accused of breaking the Covid restrictions on multiple occasions, including the ‘Bring Your Own Booze Party’ garden party at 10 Downing Street, which was revealed earlier this week.

Speaking at PMQs on Wednesday (12 January), he offered a "heartfelt apology",but said he had believed it to be a work event.

At the time, people in England were only allowed to meet up with one person they did not live with outside.

Downing Street staff are also said to have held two parties the night before Prince Philip’s funeral in April 2021 - at a time when Covid restrictions banned indoor mixing.

The events, first reported by The Telegraph, took place on 16 April and went on until the early hours.

The Prime Minister was not at either party, but it raises further questions about a culture of rule-breaking at Downing Street.

Mr Johnson has refused to be drawn on the details of his involvement in parties at No 10 and has asked people to wait until the findings of the investigation.

What will it be looking into?

Ms Gray is thought to be examining emails, calendar invites, phone messages and eyewitness accounts.

However, some reports have suggested she may also have access to CCTV and police reports.

The first goal of the inquiry is likely to be laying out a timeline for each of the nine events. Ms Gray is then expected to establish who organised them and how, who attended, and who knew about the parties.

When will the report be released?

No timeline has been released for the inquiry as of yet. Sue Gray is expected to present the results next week, but in the past it has taken months for findings of similar investigations to be reported.

Experts have also warned that it could be delayed if the police launch an investigation.

So far, the Metropolitan Police has said that it is “liaising with the Cabinet Office” and has refused to comment on the launch of a full investigation.

However, if police were to begin their own inquiry, Ms Gray’s investigation would then have to be paused, and any evidence she had uncovered handed over to officers.

The report is predominantly said to be for fact-finding and is understood to be going straight to the Prime Minister, who is then expected to be able to decide what action should be taken.

The Government’s ministerial code adviser, Lord Geidt, is understood not to be involved in the process at the moment, but if Ms Gray’s findings do suggest that a minister – including Mr Johnson – has broken the ministerial code, then Lord Geidt may have to open a new investigation.
