Constituencies represented by multiple MPs

Following the 1832 Reform Act and the 1885 Representation of the People Act, it has become common for constituencies to be represented by a single MP. Prior to these acts Parliament consisted of fewer constituencies, with some represented by multiple MPs. Those which were represented by multiple Members of Parliament are listed below, with the increase or reduction in representation being implemented at general elections held in those years.

Changes for the 2010 general election

In its fifth periodical report, the Boundary Commission for England recommended that the Hertfordshire constituencies used for the 1997, 2001 and 2005 general elections should be retained for the 2010 election. It did however suggest slight boundary changes to some constituencies, in an effort to reduce electoral disparity between constituencies. The recommendations, which became law with the Parliamentary Constituencies (England) Order 2007, also ensured that local government wards in Hertfordshire would no longer be split between two Parliamentary constituencies.

Dash (—) signifies that there were no changes.
