 It was abolished for the 1950 general election, when it was largely replaced by the new Rochester and Chatham constituency.This then became Medway in 1983.When the boroughs of Rochester upon Medway and Gillingham merged to form the larger unitary Borough of Medway in 1998, the Parliamentary constituency of Medway only covered part of the new borough, so for the 2010 election it was renamed Rochester and Strood.
