House of Lords (Hereditary Peers) Bill: motion to disagree with Lords Amendment 1

Parliament voted on 4 September 2025 to reject an amendment made by the House of Lords to the House of Lords (Hereditary Peers) Bill. The specific vote was a motion to disagree with Lords Amendment 1, which passed by 336 votes to 77. By voting to disagree, the House of Commons overturned a change the Lords had inserted into the Bill, keeping the legislation in the form the government prefers rather than accepting any modification sought by the upper chamber. The vote advances the government's plan to remove the right of hereditary peers to sit and vote in the House of Lords. Hereditary peers are those who hold their seat because of a title passed down through a family rather than because they were appointed on merit or for life. The Lords amendment that MPs rejected would have moderated the pace or scope of that removal. By disagreeing with it, MPs kept intact the government's preferred version of the Bill, which provides for complete abolition of inherited seats without a transition period or compromise arrangement. This affects the roughly 90 hereditary peers who currently remain in the Lords under an arrangement that has existed since 1999. The vote split almost entirely along party lines. Labour MPs, including those elected under the Labour and Co-operative party label, voted unanimously in favour of rejecting the Lords amendment, contributing 269 votes to the Aye side. Liberal Democrats added 57 votes and smaller parties including the Scottish National Party, Plaid Cymru, and the Greens also voted Aye. All 74 Conservative MPs who voted went into the No lobby, and Reform UK's two voting members also opposed the motion. There were no notable cross-party rebellions. The result sits within a sequence of votes on the same day: two further motions to disagree with other Lords amendments to the same Bill, Amendment 2 and Amendment 3, passed by similarly large margins of 331 to 73 and 338 to 74 respectively, confirming that the Commons systematically rejected all of the Lords' attempts to alter the legislation.
