Seaford (UK Parliament constituency)

The UK parliamentary constituency of Seaford was a Cinque Port constituency, similar to a parliamentary borough, in Seaford, East Sussex. A rotten borough, prone by size to undue influence by a patron, it was disenfranchised in the Reform Act 1832. It was notable for having returned three prime ministers as its members – Henry Pelham, who represented the town from 1717 to 1722, William Pitt the Elder from 1747 to 1754 and George Canning in 1827 – though only Canning was Prime Minister while representing Seaford.
