The seat, one of many created in 1918, was a narrower form of the oldest creation of South Northamptonshire and lasted 32 years until it reverted into "South Northamptonshire". Finally today's seat was recreated mostly from the north of the South Northants seat[n 2] in 1974. Since its recreation and during its first existence, it has been served by Conservative MPs.
