Weymouth and Melcombe Regis (UK Parliament constituency)

Weymouth and Melcombe Regis was a parliamentary borough in Dorset represented in the English House of Commons, later in that of Great Britain, and finally in the Parliament of the United Kingdom. It was formed by the Union of Weymouth and Melcombe Regis Act 1571 (13 Eliz. 1. c. 9) which amalgamated the existing boroughs of Weymouth and Melcombe Regis. Until 1832, the combined borough continued to elect the four Members of Parliament (MPs) to which its constituent parts had previously been entitled; the Great Reform Act reduced its representation to two Members, and the constituency was abolished altogether in 1885, becoming part of the new South Dorset constituency.
