A motion calling for a ceasefire in Gaza has seen the Commons descend into chaos, with procedural rows and accusations being flung around the green benches.

Wednesday was designated as an opposition day for the SNP, which chose to debate the Israel-Hamas war – and sought to persuade MPs to back its calls for an immediate halt to the fighting.

But a controversial decision from the Commons’ Speaker, Sir Lindsay Hoyle, to allow a Labour amendment to be put to the House led to an uproar from Tory MPs – and eventually saw the government pledging to “play no further part” in proceedings.

Conservative and SNP politicians have now stormed out the chamber in protest, calling for Sir Lindsay to return to the Commons and face his critics.

Politics live: Speaker sparks fury with amendments decision

Today’s debate has been the conclusion of days of drama over whether Labour would change its position on the conflict.

The party initially supported the government’s stance, calling for a pause in the fighting rather than a ceasefire, as it did not believe the latter would be sustainable.

However, after the SNP decided to force the issue to a vote in the Commons, Labour went further – putting forward an amendment calling instead for an “immediate humanitarian ceasefire”, albeit still with its initial caveats that both sides would need to lay down their arms and Israeli hostages would have to be released.

A fresh row erupted on Wednesday after Speaker Sir Lindsay Hoyle broke with convention to put Labour’s amendment to a vote – as opposition parties cannot usually amend opposition motions.

Labour sources told Sky News Sir Lindsay – who was a Labour MP before taking on the role of Speaker – had been pressurised by party whips to select it, but a party spokesman denied the claim.

However, Tory MPs are now questioning if he can stay in post, accusing him of making an “overtly political decision” to select the amendment to prevent Sir Keir Starmer facing a rebellion from his backbenchers to support the SNP’s motion.

In a surprise move, Leader of the House Penny Mordaunt announced the government would be withdrawing its own amendment to the SNP’s motion – reiterating the government’s existing position – saying the Conservatives would “play no further part in the decision this House takes on today’s proceedings”.

She said the decision of Sir Lindsay to select the Labour amendment had “raised temperatures in this House on an issue where feelings are already running high and this has put honourable and right honourable members in a more difficult position”.
