Parliament voted down a Liberal Democrat motion on sewage pollution on 23 April 2025, by 302 votes to 77. The motion called on the government to take stronger action to tackle sewage discharges into rivers and coastal waters. Opposition Day motions are non-binding debates brought by opposition parties to force the government to account for its position on a chosen issue; this one pressed the case that existing government plans fall short on water quality. The vote matters because sewage pollution in rivers and seas remains a high-profile issue affecting swimming spots, wildlife, and public health across England and Wales. By defeating the motion, the government's parliamentary majority blocked a formal expression of dissatisfaction with its approach, defending its own Water (Special Measures) Act and associated regulatory measures as sufficient progress. The result does not change the law but signals where the government stands relative to demands for faster or more ambitious action. The Liberal Democrats led the Ayes, joined by Plaid Cymru's four MPs, all four Green MPs, three Independents, one Reform UK MP, and one Democratic Unionist Party MP. All 304 Labour and Labour and Co-operative MPs who voted did so against the motion. The Conservatives, with 116 MPs, had no vote recorded. The vote sits alongside a related division on the same day in which a government amendment to the Liberal Democrat motion passed 301 to 69, indicating the government chose to substitute its own wording rather than accept the opposition's terms.
Voting Aye meant
Support stronger action to tackle sewage dumping in rivers and coastal waters, backing the Liberal Democrat position on water quality
Voting No meant
Reject the Liberal Democrat motion, either disputing its terms or arguing the government's own approach to tackling sewage pollution is sufficient
