The borough consisted of the town of Camelford, a market town in northern Cornwall, and part of the surrounding Lanteglos-by-Camelford parish. Like most of the Cornish boroughs enfranchised or re-enfranchised during the Tudor period, it was a rotten borough from the start. The right to vote was disputed in the 18th century, but according to a judgment of 1796, belonged to those "free burgesses" who were resident householders paying scot and lot. The number of voters varied as new free burgesses were created, but was estimated to be 31 in 1831. Free burgesses were made only by nomination of the "patron", who owned all the houses in the borough, and the voters always voted in accordance with the patron's instructions. The patronage, and the borough, changed hands several times. In the 1760s, before the exclusive voting rights of the free burgesses were established, the elections were managed by Charles Phillips for the government, and Camelford was considered a secure Treasury Borough. Later the power of the patron became more complete, and in 1812 The Duke of Bedford was able to sell it for £32,000, forcing its MP, Henry Brougham, to find a new seat as his radical politics were unacceptable to the new owner. From 1814 until the Great Reform Act, the owner was the Earl of Darlington. Cleveland was forced to secure his influence by regular payments to the voters, making Camelford one of the most notorious examples of corruption that were cited at the time of the Reform Act. In 1819, after two successive elections had been declared void and all the candidates disqualified for "treating", the writ was suspended, temporarily depriving the borough of its representation, although this only lasted until a new Parliament was summoned the following year. The Morning Chronicle noted in 1830 that "Everyone has heard of what Camelford cost the Marquess of Cleveland till the arrangement with the Marquess of Hertford. The Members who were returned for the marquess paid the voters in £1 notes enclosed in a deal box marked 'China'." In 1831, the borough had an estimated population of 597, and 110 houses.
