Minor changes including the gain of the two West Devon Borough wards from Torridge and West Devon and the loss of the Charterlands ward in the east to the newly named constituency of South Devon.
The areas covered in the seat were previously served by the South Hams and Plymouth Sutton seats. Both seats had been represented by the Conservative Party, and Gary Streeter, who became the first MP for the new constituency in 1997, had been MP for Plymouth Sutton from 1992 until 1997.
