Sir Lindsay deviated from standard parliamentary procedure by permitting a vote on a Labour amendment, later apologizing for this lapse but stating it was done to secure MPs' safety.

Sunak criticized the decision, warning against letting extremists influence parliamentary operations, but stopped short of endorsing Sir Lindsay's replacement.

With no formal method for MPs to remove the Speaker, his position is uncertain, especially as the SNP—Westminster's third-largest party—has withdrawn support.

This controversy arises from Sir Lindsay's authorization of a Labour amendment vote for a ceasefire in the Israel-Hamas war, during an SNP-scheduled debate, sparking an SNP uproar.

After the Conservative boycott, Labour's motion passed, eliminating further votes on other motions. Sir Lindsay defended his actions as allowing a broader vote spectrum and protecting MPs from threats. He has since been accused of playing "party politics" and intends to meet with party leaders to solidify his standing.

The Speaker offered the SNP another opportunity for a Gaza debate and stressed the severity of threats faced by MPs. Labour leader Sir Keir Starmer has denied any threats to Sir Lindsay's role, accusing the SNP of attempting to divide Labour, while the government allegedly avoided debate due to a lack of Conservative support for its amendment.

The Alba Party has requested a Commons Privileges Committee investigation into claims of undue pressure from Sir Keir.

Amid ongoing tensions in Parliament, Commons leader Penny Mordaunt criticized Labour's political maneuvering, while Conservative MPs had mixed reactions—some calling for Sir Lindsay's removal and others arguing his mistake was made with the best of intentions.

SNP MP David Linden suggested Sir Lindsay might leave his role by the week's end, while the Liberal Democrats' Ed Davey affirmed his support for the embattled Speaker.
