^On 29 May 2024, the UK Parliamentary website stated there were 345 Conservative MPs and 205 Labour MPs.

^ At the time of the dissolution of Parliament on 30 May 2024, eight of the independent MPs had been elected as Conservatives at the 2019 general election, including
Andrew Bridgen, who defected to
Reclaim in May 2023 but left the party in December 2023 and for the remainder of the 2019–2024 Parliament sat as an independent. The remaining nine independent MPs all came from the opposition benches.
^In 2019-24, the seven members of Sinn Féin abstained; i.e., they did not take their seats in the House of Commons;[9] the speaker and deputy speakers (at this Parliament's dissolution, three Conservative and one Labour) by convention exercise only a casting vote.[10]
