# List of MPs elected in the 2005 United Kingdom general election

This is a list of members of Parliament (MPs) elected to the House of Commons at the 2005 general election, held on 5 May. The list is arranged by constituency. New MPs elected since the general election and changes in party allegiance are noted at the bottom of the page.
During the 2005–2010 Parliament, Michael Martin and John Bercow served as Speaker of the Commons, Lady Hayman served as Lord Speaker, Tony Blair and Gordon Brown served as Prime Minister, and Michael Howard and David Cameron served as Leader of the Opposition. This Parliament was dissolved on 12 April 2010.

## Composition of the 2005–2010 UK Parliament

These representative diagrams show the composition of the parties in Parliament. The first show the composition immediately after the 2005 general election, and the second shows the composition before the 2010 general election.
Note: The Scottish National Party and Plaid Cymru sat together as a party group, while Sinn Féin did not take its seats. This is not the official seating plan of the House of Commons, which has five rows of benches on each side, with the government party to the right of the speaker and opposition parties to the left, but with room for only around two-thirds of MPs to sit at any one time.
| Affiliation | Affiliation | Election | At dissolution |
| | Labour Party | 355 | 349 |
| | Conservative Party | 198 | 193 |
| | Liberal Democrats | 62 | 63 |
| | Democratic Unionist Party | 9 | 8 |
| | Scottish National Party | 6 | 7 |
| | Sinn Féin | 5 | 5 |
| | Plaid Cymru | 3 | 3 |
| | Social Democratic and Labour Party | 3 | 3 |
| | Ulster Unionist Party | 1 | 0 |
| | Health Concern | 1 | 1 |
| | Respect – The Unity Coalition | 1 | 1 |
| | Independent (Peter Law; Dai Davies, Sylvia Hermon, Andrew Pelling, Bob Spink, Bob Wareing) | 1 | 5 |
| | Independent Labour (Clare Short) | 0 | 1 |
| | Suspended Labour (Elliot Morley, David Chaytor, Jim Devine) | 0 | 3 |
| | Suspended Conservative (Derek Conway) | 0 | 1 |
| | Speaker | 1 | 1 |
| | Vacant (North West Leicestershire, Strangford and Middlesbrough South and East Cleveland) | 0 | 3 |
| Total | Total | 646 | 646 |
| Notional government majority | Notional government majority | 66 | 38 |
| Working government majority | Working government majority | 71 | 48 |
Note: The effective Government majority was higher than the notional majority, because MPs from Sinn Féin did not take their seats due to their long-standing policy of abstentionism and vacant seats have no vote. Technically, the speakers belong to parties in a notional majority, though they do not usually vote and therefore don't figure in an effective majority.

## List of MPs elected in the general election

The following table is a list of MPs elected on 5 May 2005, ordered by constituency. The previous MP and previous party column shows the MP and party holding the seat at dissolution on 11 April 2005.
Note that most Scottish constituency boundaries were considerably changed from the previous general election, due to a decrease in the number of Scottish seats from 72 to 59. In this case, the previous MPs cannot be shown, and the previous party column shows the notional winner of the new seat, based on analysis of the 2001 general election result.
Key to changes since general election:
    $^a$ = change in party allegiance
