Former prime minister Theresa May joined the House of Lords in August 2024 after standing down as an MP ahead of the 2024 general election. This followed David Cameron being appointed in November 2023 to serve as foreign secretary. This page lists former UK prime ministers who have held office since 1902, together with information on whether the individuals later received a peerage entitling them to sit in the House of Lords.
Individual members of either House can propose legislation through private members’ bills (PMBs). But with limited time available, they rarely become law without government, and usually cross-party, support. This briefing looks at the 14 PMBs that the then government supported that fell at the end of the 2023–24 session. Government backing was identified by whether a government department had provided explanatory notes.
