Cornish rotten and pocket boroughs

The Cornish rotten and pocket boroughs were one of the most striking anomalies of the Unreformed House of Commons in the Parliament of the United Kingdom before the Reform Act 1832. Immediately before the Act, Cornwall had twenty boroughs, each electing two members of parliament, as well as its two knights of the shire, a total of 42 members, far in excess of the number to which its wealth, population or other importance would seem to entitle it.
