Tempers flared in the UK Parliament on Tuesday as opposition MPs launched a heated protest in the House of Commons after blocked a vote on a key amendment to the Planning and Infrastructure Bill.

The Speaker’s decision to exclude the amendment sparked uproar among lawmakers, many of whom rose on points of order, accusing the chair of undermining democratic process and parliamentary norms.

“This is a disgrace to this House,” one MP shouted, while others demanded clarification and justification for the ruling.

The blocked amendment reportedly dealt with environmental oversight and local authority powers issues opposition MPs argue are crucial to ensuring accountability in major infrastructure projects.

Footage from the Commons showed MPs visibly agitated, with some refusing to sit down and others walking out in protest. The Speaker stood firm, citing procedural grounds for the decision and warning MPs against further disruption.

This latest controversy adds to growing tensions in Westminster, where recent procedural rulings have triggered accusations of bias and calls for reform of the Speaker’s powers.

Downing Street declined to comment on the Speaker’s ruling, calling it a matter for Parliament. Opposition leaders, however, have vowed to challenge the decision and are considering measures to bring the amendment back in future debates.
