The ceremonial county of Cambridgeshire, which includes the unitary authority of Peterborough, has returned 8 MPs to the UK Parliament since 2024.
The table below shows the number of MPs representing Cambridgeshire (including Isle of Ely, Huntingdonshire and, from 1974, Peterborough) at each major redistribution of seats affecting the county.
Areas of the expanded Municipal Borough of Cambridge which had been in the Chesterton Division were now included in the parliamentary borough, with the remainder of Newmarket and Chesterton being combined to form the re-established parliamentary county of Cambridgeshire.
The Ramsey and Huntingdon Divisions were also combined to form the re-established Parliamentary County of Huntingdonshire.
The only other change affected Huntingdonshire, gaining the village of Eaton Socon, which had been in the county of Bedfordshire/constituency of Mid Bedfordshire, and had been absorbed into the Urban District of St Neots.
