Radnor (UK Parliament constituency)

Radnor or New Radnor (also called the Radnor District of Boroughs or Radnor Boroughs, especially after 1832) was a constituency in Wales between 1542 and 1885; it elected one Member of Parliament (MP) to the House of Commons of the Parliaments of England (1542–1707), Great Britain (1707–1800) and the United Kingdom (1801–1885), by the first past the post electoral system. In the Redistribution of Seats Act 1885, the division was merged into Radnorshire.

Some very notable politicians represented the constituency in the House of Commons, including Robert Harley, later Earl of Oxford and Earl Mortimer, Sir George Cornewall Lewis, and the Marquess of Hartington, later 8th Duke of Devonshire.
