British politics, particularly Prime Minister’s Questions, is often compared to a theatre.

But like many great dramas, it’s often a surprising character who provides the plot twist.

Today’s defection to Labour from the, formerly Tory, MP Christian Wakeford has managed to unite Boris Johnson’s critics and supporters on his backbenches.

One former minister, who has strongly criticised the handling of parties in Downing Street, said Wakeford had provided an “alternative target for rage” and calmed the mood in the Tory party.

Peers of Christian Wakeford, elected alongside him in 2019, have described feeling burned - “betrayed”, “let down” and upset by his actions.

In a party where loyalties were all over the place last night - Tory MPs have united in feeling his behaviour was perhaps ‘disloyalty gone one step too far’.

But this distraction doesn’t mean Boris Johnson is out of the woods. More than a dozen Tory MPs are believed to have submitted letters of no confidence in him. The exact number is still unknown. More Tory MPs are waiting until Sue Gray’s report is published before expressing their anger publicly.

Wakeford’s defection may have stuck a plaster over some of the Tory party fractures — but last night’s briefing war between different groups of the party shows just how fragile the situation still is for Boris Johnson.

Speaking during the No 10 Covid briefing that's going on at the moment, Health Secretary Sajid Javid says "we have all been pained and angered" by photos and videos of parties at Downing Street during lockdown - but it is right that Boris Johnson responds after the investigation is concluded.

Javid says the prime minister has apologised, and there needs to be "time and space for the investigation to be completed".

As Boris Johnson battles an attempt from some of his own MPs to end his leadership, it's worth recapping what exactly his Tory critics will have to do to oust him.

Under Tory party rules, forcing a vote on his leadership would require 15% of the party's MPs - that's 54 out of 359 - to submit letters of no confidence in him.

The letters have to be sent to the chair of the backbench 1922 committee, who by convention does not disclose how many have been sent in unless the threshold is reached.

If more than 50% of Tory MPs then approved a motion of no confidence in him, a leadership contest to replace him would then follow.

The Scottish Conservative leader, Douglas Ross, has said he thinks the trigger point for a no confidence vote in Boris Johnson’s leadership is “near” and “getting closer”.

Ross said he submitted a letter calling for a vote last week and would need 53 other Tory MPs to do the same for that to go ahead.

The prime minister’s spokesperson has confirmed Johnson would fight a formal attempt to oust him.

Asked why his calls for the PM to go had not been echoed by other Scottish Tory MPs, Ross said it was “perfectly legitimate” for them to reach their own conclusions.

The Scottish secretary, Alister Jack, has said he’s backing Johnson 100% and expressed hope that Ross could change his view if the PM was “exonerated”.

Health Secretary Sajid Javid is currently holding a news conference in Downing Street to outline the latest update to Covid guidelines.

The conference follows Boris Johnson's announcement to lift Plan B Covid restrictions in England, made earlier today in the House of Commons.

More now from Bury South where voters in the town of Prestwich are reacting to the news that their MP - who in 2019 turned their red wall seat blue - has now switched from Tory to Labour.

Many here told me that it was not Brexit that persuaded voters to turn to the Conservatives, but the anti-Semitism row, which persuaded them to turn away from Labour at the last general election.

One gentleman told me he doesn’t think it’s wise of Christian Wakeford to defect to Labour, as he can't see the Jewish community in the constituency - which make up around a fifth of the population - welcoming the move.

A couple of loyally Conservative-voting women told me they “really like” Wakeford as an MP. They said that he is very engaged within the community. But one of them told me that she simply cannot stomach voting for him again, as she “could never vote labour”.

However, a lifelong Labour supporter said she would now give him her vote, and believes his defection reflected well on him.

These responses from the people of Prestwich might be predictably party loyal.

But what will be interesting is whether voters feel that Labour has done enough to distance itself from the anti-Semitism row, or whether that remains an obstacle to their support for their newly Labour MP.

The Labour Party's youth wing has not welcomed the decision to accept MP Christian Wakeford.

In a tweet, Young Labour said that Wakeford had "consistently voted against the interests of working-class people".

Since the announcement from Wakeford and the Labour Party earlier today, there have been several calls for a by-election. In 2020, Wakeford supported a backbench bill, external, which called for any MP who switches parties to face a recall petition.

Labour's newest MP, Christian Wakeford, has said his decision earlier to defect from the Tories was the "hardest decision I’ve ever had to make”.

Speaking to broadcasters after signing his membership form, he said his decision to switch sides had been “many months in the build-up" and involved a "serious mount of soul-searching".

As well as the scandal over parties, he cites the Owen Paterson lobbying row, funding for free school meals, and the Dominic Cummings Barnard Castle saga as reasons for quitting the Tories.

He says there were “far too many issues where I felt we’d been on the wrong side”, and it had been difficult to explain the party's policies.

He accuses Boris Johnson of trying to “defend the indefensible” over the parties row, adding that the prime minister is now "running out of road".

Now for some parliamentary trivia that came up during PMQs.

Commons Speaker Lindsay Hoyle intervened when Labour leader Sir Keir Starmer referenced the Queen in one of his questions about Downing Street parties.

Wading in, Hoyle said: "We normally would not, quite rightly, mention the Royal Family. We don’t get into discussions on the Royal Family."

We checked this and the parliamentary rules say the Royal Family should not be discussed in the Commons, except in specific circumstances.

Paragraph 22.15 of the rules says, external:

Questions are, however, allowed on issues such as the cost of royal events and palaces.

It's been busy. Let's take a step back for a moment and reflect what’s happened so far on a day of drama in Westminster:

The 2019-ers: Overnight, it emerged that a group of Conservative MPs who won seats in traditional Labour heartlands in 2019 were reportedly plotting to remove Boris Johnson from Downing Street. This morning, there was fevered speculation about whether these MPs would push to oust Johnson from office.

Context: If 54 Tory MPs submit letters to the chairman of a Conservative Party committee, Sir Graham Brady, it would trigger a leadership contest.

PMQs: Fighting for his political life, Johnson answered MPs' questions about Downing Street parties held during Covid restrictions in a stormy session of Prime Minister’s Questions.

Labour leader Sir Keir Starmer accused Johnson of providing "absurd" defences over parties. The PM apologised for "misjudgements" but again urged MPs to wait for the results of an inquiry by senior civil servant Sue Gray.

Crossing the floor: Bury South MP Christian Wakeford dramatically defected from Tory to Labour moments before PMQs began.Tory MPs have since criticised Wakeford, with one suggesting he had made a “serious mistake”.

Mic drop: Former cabinet minister David Davis joined calls for Johnson to stand down, telling the prime minister: "In the name of God, go."

Later, Johnson's press secretary confirmed that he would fight a confidence motion, if one was called

Goodbye Plan B: In a statement, Johnson announced that England's current Covid measures - including Covid passes and face masks - were coming to an end.

Earlier on, the prime minister's press secretary addressed Christian Wakeford's departure from the Conservative Party.

She said "we're obviously sorry to see a colleague - who was elected by constituents, who voted for a Boris Johnson-led government - leave and attempt to put Keir Starmer into No 10, which will be a disaster for the country".

As Wakeford switched to Labour earlier today, he accused the prime minister of being "incapable of offering the leadership and government this country deserves".

A Labour spokesman said the party had been in talks with Wakeford for "some time" and their contact started before the Downing Street party allegations.

Jackie Patchick, left, voted for MP Christian Wakeford in the last election. She says she likes him and always votes Conservative. Jackie is disappointed that he switched to Labour today and she isn't sure if she will vote for him in the next election.

Adele Frieslander, above right, likes Wakeford as an MP and but says she will really have to think about whether she will vote for him next time, now that he is with Labour.

Alice Beesley has always voted for Labour and she says that she would never vote for the Tories. Now that Wakeford has switched, Alice thinks she would vote for him and thinks the move reflects well on him.

Meanwhile, David, below, says he is not sure if it was a wise move for the MP. He says the Tories only won the seat last time because of Labour's anti-Semitism row. David wonders if the large Jewish community in Wakefield's constituency would accept him now that he has defected.

A cabinet minister loyal to Boris Johnson has accused Tory rebels plotting to oust the PM of "playing schoolboy politics", adding "it's running into the ground".

"I'm hearing letters are being removed as they lose their bottle," the minister adds.

But another MP tells me this claim is "rubbish" - and the division in the Tory party between Remainers and Leavers is being replaced by factions for and against the prime minister.

It is fair to say that David Davis's intervention at PMQs won't necessarily unleash another load of calls for the prime minister to resign.

However, it is a clear demonstration that there is unhappiness with the PM in different parts of the Tory party, not just among MPs elected in 2019.

And amid claims that the mood among Tory MPs is calming, Treasury Chief Secretary Simon Clarke has brushed off a call by senior Tory David Davis for Boris Johnson to resign as prime minister.

"I disagree very strongly with David Davis, I disagree very strongly with Christian Wakeford [who defected to Labour earlier], he told BBC Radio 4's The World at One.

"The prime minister was very clear we will get on with the job of getting the country through the pandemic," he says.

"The priority now is to make sure that this country which has, like much of the world, gone through such difficult times in the last two years is now in a position to come out of the pandemic really strongly. We have the strongest economic growth in the world.

"I am fully supportive of the prime minister."

A former cabinet minister has told the BBC that Christian Wakeford's defection has "provided an alternative target for rage".

The senior Tory MP said Wakeford's defection had "calmed" the mood on the Conservative backbenches.

They said his defection was the "discussion of the hour" and lots of Tory MPs were "venting" frustration about it - both Boris Johnson loyalists and those who were "very upset" with the prime minister last night.

They criticised Wakeford's behaviour and the timing of his defection before PMQs.

As we've been reporting, MP Christian Wakeford left the Conservative benches and walked across the floor to join Labour this lunchtime.

So what do constituents think of the Bury South MP's dramatic defection?

At Rosylee coffee house, opposite Wakeford's office, Debbie Clark, 52, says she voted Conservative for the first time at the last election.

“I am disgusted,” she tells me. “I voted for the party. He should resign and we should have an election.”

Her husband Fred agrees: “He should not have the right to go to Labour."

On the table next to them is 51-year-old Maxine Ballington. She also voted Conservative.

She too is shocked by today’s defection but wants Boris Johnson to resign.

“I’ve lost two people to Covid. People were fined for having house parties. How can he go to a party at Downing Street?” she says.

Outside Wakeford's constituency office one man told me he wasn’t surprised.

But as he waits to pick up his wife from a beauty salon, he insists the prime minister hadn't done anything wrong and described the defection an overreaction.

Prime Minister Boris Johnson's press secretary has confirmed that he will fight a confidence motion, if one is called.

Asked if the prime minister still thought he was the best man for the job, his press secretary replied: "Yes."

She said the prime minister would continue meeting with MPs this afternoon.

She also denied reports that Johnson had been in tears at a meeting yesterday and said that he was "entirely focused on his job and on delivering for the British people".

A Labour spokesman has indicated the party's leader believes there will be no need to hold a by-election in Bury South following Christian Wakeford's defection.

Asked if, as far as Sir Keir Starmer is concerned, there is no principle requiring anyone who defects from one party to another to stand for re-election, the spokesman said: "Correct."

On whether Wakeford will face a trigger ballot in the coming months, the spokesman added: "We'll set out all of the process, obviously, once we've had a chance to speak to people, the relevant people that vote in the local party and nationally, and we'll happily set out the process at that point.

"But I don't want to pre-empt that now."
