An election to Slough Borough Council was held on 10 June 2004. The whole council was up for election. This was the 120th Slough general local authority election, since Slough became a local government unit in 1863, including both whole Council elections and elections by thirds. The Borough had been re-warded for this election. For the previous three Slough elections, which had each returned a third of the council, see 2001 Slough Council election, 2002 Slough Council election and 2003 Slough Council election. The 2004 election was to fill forty-one seats. The leading vote winner in each of the fourteen wards was elected for the term 2004–2008. The second placed candidates were elected for 2004–2007. In all the wards, except Colnbrook with Poyle, the candidate with the third highest number of votes was elected for the term 2004–2006. Recent political history of Slough to 2004 Slough Borough Council, between 1983 and 2004, had been controlled by the Labour Party. Between 2003 and 2004, there were three groups of Councillors. In addition to the Labour Group and the Conservative Group there was the Britwellian, Independent, Liberal and Liberal Democrat Group (BILLD). The BILLD Group was composed of all the Councillors, who were not Labour or Conservative. It was a coalition of a number of parties and independents. These included a Councillor or Councillors elected in particular wards; Liberal Democrat (Foxborough ward), Liberal (Haymill ward), Independent Britwellian Residents (Britwell ward) and Independent (Wexham Lea ward). The existing members of the Group had an electoral pact for the 2004 election, which also extended to the Independent Farnham Residents candidates in Farnham ward and the Independent Langley Residents candidates in Langley St Mary's ward. In 2003–2004, the composition of the 41 member council was:- Labour 26 BILLD 9 (Independent Britwellian Residents 3, Slough Liberals 3, Independents 2 and Slough Liberal Democrat 1) Conservative 6 In the 2004 election 105 candidates were nominated for the 41 seats up for election.
