British Prime Minister Rishi Sunak has said that a decision by the House of Commons speaker to break with procedure due to threats facing some lawmakers over their views on the Gaza conflict sent a dangerous signal that intimidation works, Reuters reports.

Parliament descended into chaos on Wednesday night as tensions flared over a vote on whether to call for a ceasefire in Gaza and the exact language to use.

The speaker of the lower house, Lindsay Hoyle, said he broke with usual parliamentary procedure for the vote because of what he described as “absolutely frightening” threats against lawmakers.

“In parliament this week, a dangerous signal was sent that intimidation works,” Sunak said in a post on X.
