• The Municipal Borough of Hertford; • The Urban Districts of Stevenage and Ware; and • The Rural District of Hertford. Hertford and its rural district had previously been in the
Hertford constituency, Stevenage in
Hitchin and Ware in
Hertfordshire East. After being used for only three general elections, a further round of boundary changes in 1983 saw Hertford and Stevenage abolished, with Hertford and Ware joining Bishop's Stortford in
Hertford and Stortford while the remainder of the seat formed the basis of the new
Stevenage constituency. ==Members of Parliament==
