Rishi Sunak calls Sir Lindsay Hoyle's decision to break with convention on a Gaza ceasefire vote "very concerning"
The PM says "we should never let extremists intimidate us" into changing how Parliament works, after Hoyle allowed a vote on a Labour amendment to an SNP proposal
It comes after the SNP's Westminster leader tells Hoyle his party has no confidence in him as Commons Speaker after yesterday's debate chaos
More than 60 MPs now say they have no confidence in Hoyle, who has apologised twice for making the "wrong decision"
Meanwhile, Labour leader Sir Keir Starmer has denied threatening Hoyle, saying he “simply urged” the Speaker to ensure there was the “broadest possible debate”
On Wednesday, MPs approved a Labour motion calling for an "immediate humanitarian ceasefire" following hours of debate which saw SNP and Conservative MPs walk out of the Commons

Sunak repeats that the Post Office Horizon IT scandal is "one of the greatest miscarriages of justice in a country's history".
He also hits out at Starmer, saying he does not recall him raising the scandal in any of their PMQs exchanges over the past year.
He pushes again that the inquiry is the "right and proper way to get the truth the victims deserve".
Acknowledging that the Post Office inquiry is ongoing, Starmer asks Sunak why he doesn't release all of the correspondence relating to the Horizon scandal.
He quotes victim Chris Head, who has said it's his view that there is a lack of transparency in the process.
Image source, PA MediaSunak says the "right way" is to set up an independent inquiry into the Horizon scandal, which the government has done.
He, again, says they are focusing on getting compensation to victims.
Starmer continues asking about the 2016 investigation into whether Post Office branch accounts could be altered, which was stopped by the government the day before it was completed.
What did government ministers know about it at the time, he asks?
Sunak hits back, by saying that while Starmer picked one particular date, it is worth "bearing in mind this scandal has unfolded over decades".
He says the government is focused on getting compensation and justice for victims, adding that two-thirds of people have received "full and final offers".
Starmer says information about a 2016 investigation - trawled 17 years of records to find out how often, and why, cash accounts on the Horizon IT system had been tampered with remotely - has just come to light this week.
It comes after the BBC revealed that David Cameron's government knew the Post Office had ditched a secret investigation that might have helped wrongly accused postmasters prove their innocence.
He points out the current foreign secretary, David Cameron, was running the government at the time of the scandal.
He says: "Has (the PM) thought to ask either of them what they knew in 2016?".
Sunak responds by standing by his business secretary, saying she asked the former head of the Post Office to step down over "serious concerns".
The prime minister says the Post Office scandal is one of the "greatest miscarriages of justice in the country's history", and that the government is working hard to ensure the victims get the "justice and compensation they deserve".

Starmer presses on, saying Kemi Badenoch categorically denied the claims about compensation to postmasters being delayed.
However, he says a note from Staunton published this morning "appears to directly contradict that".
He asks the PM to investigate this properly, and asks "why, rather than taking those accusations seriously, she accused a whistleblower of lying?"
PM challenged to repeat Badenoch’s Post Office claims
Prime Minister Rishi Sunak replies by saying Kemi Badenoch told the House on Monday that she asked Henry Staunton to step down after "serious concerns" were raised.
He adds that the government has already taken "unprecedented steps" to ensure that victims of the Post Office Horizon IT scandal get the compensation they need.
Image source, PA MediaPMQs kicks off with Labour leader Keir Starmer joining the prime minister in expressing his "disgust" at the death of Alexei Navalny in Russia.
He says Russian President Vladimir Putin "has stolen not just the wealth, but also the future and democracy of the Russian people".
On another note, the Labour leader asks Sunak whether he is prepared to repeat an allegation that the former Post Office chair Henry Staunton was lying about a row over compensation payments.
Image source, PA MediaSunak begins by extending his deepest condolences to the family of Alexei Navalny, a Russian opposition leader who was found dead in a penal colony last week.
Sunak says Navalny died for a cause to which he dedicated his whole life - "freedom".
"This morning we had meetings with ministerial colleagues, and highlighted how the government has sanctioned the prison officials at the penal colony where Navalny was held," he says.
Sir Keir Starmer echoes these condolences to Navalny's family.

Both Rishi Sunak and Sir Keir Starmer will be feeling a little bruised as they make their final preparations for Prime Minister’s Questions.
There are a whole range of uncomfortable questions for Sunak this morning.
Did the government want the Post Office to “hobble” into the election without solving the company's long-term problems, as alleged by its former chair Henry Staunton? Does the failed test firing of a Trident missile from a Royal Navy submarine raise concerns about the UK’s nuclear defences? And what about the government’s sacking of its own immigration watchdog?
But Starmer is coming into PMQ’s with concerns of his own. He will no doubt want to highlight the party’s two new MPs after his double by-election victory last week. But Labour’s position on the Israel-Gaza conflict is once again in the spotlight ahead of the vote on a ceasefire this afternoon.
It could be a tricky day for both men.

One topic likely to crop up at PMQs is the test firing failure of the UK's Trident nuclear missile, which emerged last night.
Defence Secretary Grant Shapps witnessed the test, in which it is reported the booster rockets failed and the missile landed in the sea close to the launch site.
A defence source close to Shapps has said the failure was "specific to the event" and there is "no doubt" the UK would be able to fire "in a real world situation if we needed to".
But Labour has called for assurances over the effectiveness of the nuclear deterrent with John Healey, the shadow defence secretary, branding the failure "concerning".
The Ministry of Defence, meanwhile, insists the "nuclear deterrent remains safe, secure and effective".

All of the political action today comes as a general election approaches, likely later this year.
On average, Labour has an 18 percentage point lead over the Conservatives in the latest opinion polls.
Labour’s average vote share is about 43% compared with the Conservatives on 25%, while the Liberal Democrats and Reform UK are on about 10% each.
The latest figures come from polls conducted by 11 different companies over the two weeks up to 19 February.
Have a look at our general election poll tracker to see how things have changed over the past 12 months and since 2020, as well as all the individual polling company data.
Image source, BBC NewsThe Conservatives suffered two by-election defeats last week in Wellingborough in Northamptonshire and Kingswood in South Gloucestershire, with Labour overturning big Conservative majorities.
In Wellingborough, Labour won Peter Bone’s former seat, which he had held with a majority of more than 18,000. And in Kingswood, the party overturned an 11,220 Conservative majority.
Rishi Sunak said there were “particularly challenging” circumstances in the two defeats, and called on the country to "stick with" his government.
The results mean the Tories - who are trailing a long way behind Labour in national opinion polls ahead of a general election due this year - have suffered ten by-election losses in this parliament, more than any other government since the 1960s.

Image source, UK ParliamentNow for the latest instalment of the Post Office scandal.
Its former chairman has claimed he was told to "hobble" into the next election without solving the company's long-term problems.
Henry Staunton, who was sacked last month, said the comment was made by a senior civil servant during a meeting last year.
On Monday, Business Secretary Kemi Badenoch denied he had been told to stall payments, saying there was "no evidence" to support the claim.
With the row over his departure deepening, Mr Staunton has now disclosed a memo of an introductory meeting he had in January last year with Sarah Munby, then the most senior civil servant at the business department.
In the note, first published by the Times and seen by the BBC, he recorded that Ms Munby warned him that "politicians do not necessarily like to confront reality", and there was no appetite to "rip off the band aid" regarding the Post Office's finances.

There are four big political stories in the mix this morning - on Gaza, the Post Office, immigration and Trident.
MP's will this afternoon debate an SNP call for an immediate ceasefire in Gaza, which is likely to test Labour's stance on the issue
Second is the continuing Post Office scandal fallout, with an ongoing row between Business Secretary Kemi Badenoch and the ex-Post Office boss, Henry Staunton, who she sacked.
Staunton claims he was told to delay Horizon compensation payments for sub-postmasters, but Badenoch has denied this and PM Rishi Sunak has backed her.
Third is the dramatic sacking of the independent immigration watchdog, David Neal, last night, following leaked news stories from 15 of his reports that remain unpublished.
Fourth is concern over the embarrassing failure of the UK's nuclear deterrent, Trident, in Royal Navy tests for the second time in a row, with Defence Secretary Grant Shapps expected to give reassurances at the dispatch box this afternoon.
Jess Phillips quit her role in the shadow cabinet last year after defying what was then Labour's official stance and voting for a ceasefire
The last time there was a vote on a ceasefire in the House of Commons, a large number of Labour MPs rebelled against the party stance.
The vote last November was on an SNP amendment to a government motion, calling for an end to the "collective punishment of the Palestinian people" and urging "all parties to agree to an immediate ceasefire".
It was defeated by 125 votes to 294, with the 56 Labour rebels joining other opposition parties to demand a ceasefire.
Jess Phillips, Afzal Khan and Yasmin Qureshi were among shadow ministers who quit their roles to back the motion from the SNP.
Announcing she was quitting her role as shadow domestic violence minister, Phillips said she was voting with "my constituents, my head, and my heart".
