It's been an eventful 24 hours. Given recent developments - from sackings to resignations - we're all in need of a quick round-up of where we're up to on this political saga.

• Michael Gove, former levelling up minister, has been sacked by Boris Johnson. No 10 sources called Gove a "snake", adding it's not possible to have someone in cabinet "who gleefully tells the press the leader has to go"
• Secretary of State for Wales Simon Hart became the third cabinet minister to resign from the PM's government as he called on the PM to resign
• Hart was part of a group of cabinet ministers - including Home Secretary Priti Patel - who visited the PM this evening telling him to quit
• Attorney General Suella Braverman told ITV's Robert Peston she will be standing in any leadership contest. Braverman has called on the PM to resign, but she hasn't resigned from Johnson's cabinet because "we need an attorney in government"
• Since Sajid Javid's resignation as health secretary on Tuesday, more than 40 further ministers and aides have quit Johnson's government
• PM's aide James Duddridge said Nadhim Zahawi, the newly appointed chancellor, was "solidly behind the prime minister, despite earlier reports that he was part of the group of cabinet ministers calling on Johnson to resign

Nadhim Zahawi, who was only appointed as chancellor on Tuesday, is "solidly behind" the prime minister, Boris Johnson's parliamentary private secretary has told Sky News.

Zahawi was earlier reported to have been in No 10 Downing Street as part of a group of cabinet ministers telling Boris Johnson that he should resign.

But James Duddridge told Sky News earlier that those reports are "wrong" and Zahawi will be announcing a new economic strategy "some time next week".

Duddridge was emphatic that the PM would "go on and deliver".

Conservative MP Gareth Davies has quit as parliamentary private secretary to the Department of Health and Social Care.

The Grantham and Stamford MP tweeted: "It is with great regret that I have informed the whips office of my resignation as a PPS at the Department of Health and Social Care.

"It has been a privilege to serve in the role and not a decision I have taken lightly."

With a third of the government gone following the stream of resignations, can it still be described as functioning?

Not according to Camilla Cavendish, the former director of the Number 10 Policy Unit. "The key point here is exactly this - we don't have a functioning government," she tells the BBC.

"As of tonight there aren't enough people to keep the business of the government going. Members of Parliament have already been told there aren't even enough people on the bill committees to actually get the legislation through - that is the fundamental business of government."

Cavendish adds: "He can try in the next few days to bring new people in and there's always bound to be somebody but he is going to run out of road."

Conservative backbencher Bob Seely has been speaking to BBC Radio 4about Boris Johnson’s refusal to resign.

Speaking to the World Tonight, he said it's not a case of thecalm before the storm, but rather "the storm before the calm".

He added the political crisis was "a bit like the end of abad relationship - it's just emotionally exhausting".

"You think well I've tried, it hasn’t worked, we've givenit a few years and we need to move on."

Seely has withdrawn his support for Johnson after backing him inlast month’s vote of confidence. He's now hoping there will be a second vote.

Speaking to the BBC, former Conservative minister Margot James criticised Boris Johnson's decision to sack Michael Gove.

After losing more than 40 ministers in 24 hours, she said it was "grossly irresponsible" to sack "probably the most competent minister in the whole cabinet".

James added she suspected it was "active vengeance for what happened three years ago".

In 2016, when David Cameron stepped down, Johnson dropped out of the race for the Conservative leadership bid when Gove - who had previously backed Johnson - announced his own bid. Theresa May went on to win, becoming PM.

And in 2019, Gove took Johnson on again, after having previously backed him to replace May when she resigned.

Matt Hancock - the former health secretary - says "it's clear" Prime Minister Boris Johnson needs to resign.

In an interview with ITV's Robert Peston, Hancock says it's a sad end for Johnson.

He adds: "It's clear whether it's tomorrow or next Tuesday, there's going to be a new prime minister".

As we've been hearing, Attorney General Suella Braverman has called on the prime minister to resign - and also said she'd stand for the party leadership. and stated her leadership interests.

Jason McCartney, parliamentary private secretary to the attorney general's office, has just tweeted his backing: "I agree with my boss the attorney general".

The government's Attorney General Suella Braverman says it's "time to go" for Boris Johnson.

But despite calling on Prime Minister Boris Johnson to resign, she tells ITV's Robert Peston she will continue in her role.

Braverman adds "I don’t want to resign because I have that duty and we need an attorney in government”.

"The balance has tipped now in favour of saying that the prime minister - it pains me to say it - but it's time to go."

Asked whether she's considered standing in any leadership contest, she says she would put her name into the ring.

It's getting late, but the resignations keep on coming. We're just hearing that health minister Ed Argar has also resigned from Johnson's government.

Simon Hart, MP for Carmarthen West and South Pembrokeshire, had been a part of Boris Johnson's cabinet since 2019.

In his resignation letter he said PM will be remembered with "energy, vision, determination and humour",

Hart said he had never been a "massive fan of ministerial resignations being the best means of forcing change".

But, he adds, it's now past the point where utmost support to help the PM "turn the ship around" is enough.

Hart was thought to be among a group of cabinet ministers who reportedly wentinto No 10 earlier today to tell Johnson it was time to go.

Yesterday, Hart made it made it clear to No 10 that it was "game over" but it shouldn’t have to come by ministerial resignations.

Simon Hart, former secretary of state for Wales, has just resigned, bringing the number of cabinet members who have resigned up to three - alongside Sajid Javid and Rishi Sunak.

In his resignation letter to Boris Johnson, Hart says: "I had desperately hoped that I could avoid writing this letter, but alas there seems no other option left but to step down from my role as secretary of state for Wales".

He adds: "Colleagues have done their upmost [sic] in private and public to help you turn the ship around, but it is with sadness that I feel we have passed the point where this is possible".

So far 43 ministers and aides have resigned from Johnson's government.

As a rule of thumb, you can define the significance ofthe occasion by the number of cameras in Downing Street.

In the summer sunshine, the street was as busy as it wasin the cold of Christmas Eve 2019 when the Brexit deal was about to be struck.

The Transport Secretary Grant Shapps strode towards No 10, making very public his role as a messenger telling the prime minister what he didn't want to hear.

Equally publicly, staunch supporter Nadine Dorries arrived at No 10 to express her loyalty.

It's a great British tradition for the massed ranks of the media to shout questions at ministers, rarely expecting a reply.

But when she left not only did she say that she supported Johnson but when asked if any of her colleagues still did she emphatically declared "yes, definitely" - suggesting the PM wasn't ready to throw in the towel.

Anne Marie Trevelyan followed in her wake but was tight-lipped on whether she was still in support.

And the Home Secretary Priti Patel avoided the glare of the cameras entirely - delivering her blow to the PM in private.

All this has taken place against a soundtrack of an anti-Boris Johnson demonstrator blaring out 'bye bye Boris' to the tune of the similarly titled Bay City Rollers hit, occasionally drowned out by the strains of a marching band practicing in nearby Horse Guards Parade and a helicopter overhead.

Tim Loughton, Conservative MP for East Worthing and Shoreham, has a novel take on Boris Johnson's firing of Michael Gove.

He tells Sky News that Michael Gove offered Johnson the "metaphorical bottle of whisky and the revolver".

"Well clearly Boris has downed the whisky and turned the revolver on Michael Gove.

"Who would have believed it?"

Meanwhile, there have been three more resignations from Johnson's government. Taking the number of ministers and aides that have resigned - or been sacked - up to at least 41.

Danny Kruger has now resigned as parliamentary private secretary to the Department of Levelling Up, Housing and Communities - Michael Gove's former department.

Kruger says he's "very sorry indeed to hear Michael Gove has been fired".

James Daly, parliamentary private secretary to the Department of Work and Pensions, resigned from his role "with great regret".

We've been hearing from a No 10 source who has been talking about why the PM is staying on.

"There is no lectern outside No 10 tonight... the PM fights on," the source says.

Any suggestion there's a procession of cabinet ministers telling Johnson to go "is not true", the source claims, adding: "He's called their bluff."

"He has been spelling out to them [cabinet ministers] that 14 million people voted for him," the source says, adding that if the Conservative Party "want to deprive him [Johnson] doing that job, they have take to take that mandate off them".

The source adds that Johnson explained to cabinet ministers tonight that the options are not "Boris or no Boris".

Rather, it's about giving Johnson either a "fresh chancellor and new programme, that Rishi was not prepared to do" or "spend months ripping each other apart to elect a leader without a mandate - coalition of chaos and Labour who will break up Britain".

Michael Gove is a senior and long-standing figure in the Conservative Party and has served in a strong of high-level posts, from his 2010 appointment as Education Secretary onwards.

He has been Chief Whip, Chancellor of the Duchy of Lancaster, Justice Secretary and Environment Secretary, as well as the role he was just sacked from, Secretary of State for Levelling Up, Housing and Communities.

Gove worked closely with Johnson on the Vote Leave Brexit campaign.

He has remained loyal to Johnson since he became prime minister. However, during the 2016 Conservative leadership race he initially backed Boris Johnson but later dramatically withdrew his backing, announcing he would run himself. That contest was ultimately won by Theresa May.

Gove also ranagainst Johnson in the 2019 Tory leadership race.
