A Labour frontbencher has defied Sir Keir Starmer with a pledge to back calls for a ceasefire in Gaza in a crunch Commons vote.
Naz Shah, shadow minister for crime reduction, broke ranks with her party leader as she confirmed plans to vote for an SNP amendment to the King’s Speech backing a ceasefire.
Labour frontbenchers are facing the sack if they back the amendment, as Sir Keir bids to avoid a damaging split in his parliamentary party.
Labour MPs have been ordered to abstain on the SNP move and have instead been told to back Sir Keir’s position calling for longer “humanitarian pauses” rather than a ceasefire.
SNP Westminster leader Stephen Flynn has said Parliament must “show moral leadership” and vote in favour of backing an immediate cessation of hostilities.
Labour frontbenchers who rebel to back a rival amendment would normally face the sack for breaking the party whip.
Ms Shah said a “humanitarian catastrophe” is taking place in Gaza as she backed calls for an “immediate ceasefire”.
She told the Commons: “I will be supporting the amendment which seeks an immediate ceasefire.”
The Bradford West MP also invoked Robin Cook, who resigned from Sir Tony Blair’s Cabinet over the invasion of Iraq in 2003.
“Make no mistake, this is a humanitarian catastrophe which is why I urge members to back an immediate ceasefire on all sides and push for the release of hostages,” she said.
Both Labour’s amendment and the SNP’s one have been selected for a vote on Wednesday evening by Commons Speaker Sir Lindsay Hoyle.
A party spokesman earlier said: “This is a whipped vote and every MP knows what the consequence of that means.”
The party position on the Middle East conflict has led to internal splits, with the leadership backing the UK Government’s position of pushing for humanitarian pauses in the fighting to allow aid to reach Palestinians trapped in the bombarded territory but stopping short of calling for a total cessation of hostilities.
However, several shadow ministers have openly called for a ceasefire and dozens of councillors have resigned from Labour over its refusal to back a permanent halt to the violence.
People know that what we are all watching in Gaza is wrong— Stephen Flynn, SNP
In a letter to MPs, the SNP’s Mr Flynn wrote: “By refusing to join the United Nations in pressing for an immediate ceasefire, Westminster would be disregarding international law, condoning collective punishment and giving the green light to the continued bombardment of Gaza, which has seen thousands of innocent children and civilians killed.
“People understand that the conflict in the Middle East is full of complexity. But amidst all that complexity, they also recognise a very human truth. People know that what we are all watching in Gaza is wrong and they want their MPs to do the right thing, show moral leadership and press for an immediate ceasefire.”
By tradition, those occupying frontbench positions are bound by a collective responsibility that they support the party’s position but, so far, Sir Keir has allowed some to deviate by expressing support for a ceasefire in Gaza.
But the Labour spokesman said that “space” for debate did not extend to a vote in Parliament because “that has a significance to it that everybody understands”.
The Commons showdown comes as Israeli forces entered Gaza’s Shifa hospital.
The Israeli army had surrounded the facility as part of its ground offensive against Hamas, claiming the militant group conceals military operations in the complex.
But with hundreds of patients and medical personnel inside, the move risks civilian casualties.
Hamas raids on October 7 killed 1,200 people in Israel and saw more than 200 taken hostage.
Retaliatory strikes, including a ground offensive into northern Gaza, by Tel Aviv’s forces have killed more than 11,000 Palestinians, according to the Hamas-run Gaza health ministry.
Foreign Office minister Andrew Mitchell is in Cairo on Wednesday to hold talks with Egyptian counterparts and other partners on how to get more humanitarian aid into Gaza.
