Peterborough City Council is the local authority of Peterborough in Cambridgeshire, England. It is a unitary authority, having the powers of a non-metropolitan county and district council combined. The City of Peterborough in the East of England was incorporated as a municipal borough in 1874; from 1888 it fell within the jurisdiction of the Soke of Peterborough county council and from 1965 Huntingdon and Peterborough county council. In 1974 it was replaced by a wholly new non-metropolitan district, broadly corresponding to the Soke, in the new enlarged Cambridgeshire. In 1998 Peterborough became independent of Cambridgeshire as a unitary authority, but the city continues to form part of that county for ceremonial purposes as defined by the Lieutenancies Act 1997.
