The 2003 Plymouth City Council election was held on 1 May 2003 to elect members of Plymouth City Council in England. This was on the same day as the other local elections. The election was the first to be contested under new ward boundaries, and as a result the entire council was up for election. The Labour Party regained control of the council, which it had lost to the Conservative Party at the previous election in 2000.[1] [2] [3]
