How many MPs are there in Parliament?

There are 650 MPs in the House of Commons, one for each constituency. The number was fixed at 650 by the Parliamentary Constituencies Act 2020, and the current boundaries were first used at the July 2024 general election.

The party breakdown changes between elections through by-elections, defections and the whip being withdrawn or restored. On 13 October 2026 Parliament's members data listed Labour 404, Conservative 118, Liberal Democrat 71 and 11 Independents, with the rest held by smaller parties and the Speaker. For the latest count, use the Commons state of the parties. Sinn Féin MPs do not take their seats, and the Speaker and deputy speakers do not normally vote, which matters when working out a majority.

When is the next figure out?

Hansard is published on every sitting day, with Commons debates normally online within a few hours and division lists soon after each vote. Written answers appear on the questions site once departments submit them, usually the same day. The Commons register of interests is updated regularly, roughly fortnightly when the House sits, and MPs must register new interests within 28 days. IPSA publishes MPs' business costs every two months, covering claims processed four to five months earlier, and announces MPs' pay for the year from April. Parliament's calendar shows sitting days and recess dates.

Every official release due in the next two weeks is on the release calendar.
