The third largest party in the House of Commons, the SNP, says it doesn't have confidence in its Speaker, Lindsay Hoyle.
The Speaker himself says he took decisions about how MPs debated and voted on calls for a ceasefire in Gaza because he wanted as broad a discussion as possible.
He's apologised but said the safety of MPs on such a divisive issue was also on his mind.
With thousands dead in Gaza and war continuing, the optics of MPs rowing about Commons procedure - rather than debating important international issues - have not sat well with everyone.
Niall Paterson speaks to Dr Hannah White from the Institute for Government about why she thinks it's another example supporting the case for parliamentary reform.
Conservative MP Tobias Ellwood describes it as his "worst day in Parliament". He recently had dozens of anti-Israel protesters gather outside his home.
And chief political correspondent Jon Craig picks over how the chamber moves on from this - and whether Lindsay Hoyle will stay in his job.
