2024 London Assembly election

The 2024 election to the London Assembly was held on 2 May concurrently with the London mayoral election and local elections across England and Wales.

Background
In the 2021 London Assembly elections, Labour won eleven seats, the Conservatives nine, the Green Party three, and the Liberal Democrats two.

The 2024 election was one of several local elections (and one parliamentary by-election) that took place on the same day, across England and Wales.

Electoral system
Members of the London Assembly are elected through a combination of both first past the post and closed list proportional representation. This system is commonly referred to as the additional member system. Fourteen members are elected in single member constituencies with the candidate receiving the largest number of votes becoming the Assembly Member for that constituency. An additional 11 members are also elected from the whole of London, with parties submitting lists of up to 25 candidates. For a party to be included, it needs to attain at least 5% of the vote across London. This process divides the remaining seats proportionally to the vote share of the parties with the use of the modified D'Hondt method allocating the seats. This system ensures overall proportionality with the 11 additional members being allocated in a corrective manner.

Constituency candidates need to submit a deposit of £1,000, which is returned if they get at least 5% of the vote. A London-wide list requires a deposit of £5,000, which is returned if the list gets 2.5% of the vote.
