But the Institute for Government, an independent think tank focused on effective government in the U.K., criticized politicians on all sides of the issue for allowing a meaningful debate on Gaza to descend into “embarrassing chaos.”

All of the parties are being disingenuous about their motives, with the government and SNP mostly upset, because they lost an opportunity to highlight the divisions within Labour over its Gaza policy, Hannah White, the institute’s director, wrote in an analysis published Thursday.

Labour, trying to balance pressures from pro-Israel and pro-Palestinian supporters, only recently changed its policy to support calls for an immediate cease-fire in Gaza.

“Political game-playing over parliamentary procedure is unedifying at the best of times, but for parliamentarians to behave in this way during a debate about a conflict in which tens of thousands are dying has undoubtedly brought Parliament into disrepute,” White said.
