There has been an increase in the use of citizens’ assemblies over recent years in the UK and Ireland. Assemblies have been set up to consider subjects such as English devolution, adult social care and a range of different matters in Ireland (including the abortion laws and climate change). These have been arranged by a range of bodies, including think tanks, academic institutions, parliamentary committees and, in the case of Ireland, the parliament itself. In addition, some people have recommended the use of a citizens’ assembly to decide how to proceed with Brexit. Indeed, the University College London’s Constitution Unit did lead a citizens’ assembly on Brexit in 2017, which considered the UK’s future relationship with the EU, particularly in relation to migration policy and trade policy. The public participation charity Involve has stated that citizens’ assemblies can provide a high profile way of analysing complex issues and offer policymakers an insight into public opinion. However, it has also stressed that running them can be challenging and expensive, and that there could be a danger of it being viewed as a publicity exercise if not followed by real outcomes.

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.
