This article details the results of Elections to Preston City Council held in May 2003
Preston Council is elected "in thirds", which means in 2002 the entire council was up for election and in subsequent years one councillor from the three-member wards and one councillor from selected two-member wards defend their seat. In these result tables, the share of the vote is blank as the 2002 elections cannot be fairly compared. Any gain or loss can be recorded as each year the councillors are defending their ward results.
