Britain's Labour Party Backs Election Ahead Of Second Vote

The video discusses the rejection of a vote in the House of Commons, which required a 2/3 majority for a December 12th election. Boris Johnson plans to introduce a bill needing only a simple majority. Labour Party leader Jeremy Corbyn, previously against an election without a no-deal Brexit assurance, now supports it.
