{{Main|List of parliamentary constituencies in Cornwall}}
Until 1832, Cornwall was represented by 44 [[Member of Parliament (UK)|Members of Parliament]] (MPs) in the [[House of Commons (UK)|House of Commons]]—more than any other county—reflecting the importance of tin mining to the Crown.<ref>{{cite web |url=http://www.britarch.ac.uk/ba/ba31/ba31regs.html |title=British Archaeology, no 30, December 1997: Letters |publisher=Britarch.ac.uk |access-date=25 September 2010 |archive-date=13 February 2011 |archive-url=https://web.archive.org/web/20110213215034/http://www.britarch.ac.uk/ba/ba31/ba31regs.html |url-status=live }}</ref> Most of the increase in numbers of MPs came between 1529 and 1584 after which there was no change until the [[Reform Act 1832]],<ref>[[A. L. Rowse|Rowse, A. L.]] (1941) ''Tudor Cornwall''. London: Cape; pp. 91–94</ref> which enacted widespread changes to the country's [[electoral system]] and reduced Cornwall's number of MPs to 14. This was reduced further in subsequent [[Boundary commissions (United Kingdom)|boundary commission]] reviews to better reflect Cornwall's population. The county is currently divided into [[List of Parliamentary constituencies in Cornwall|six county constituencies]].

The [[Liberal Party (UK)|Liberal Party]] and its successor, the Liberal Democrats, have traditionally been popular in Cornwall; the Liberals won every Cornish seat in [[1906 United Kingdom general election|1906]] and [[January 1910 United Kingdom general election|January 1910]], and again in [[1929 United Kingdom general election|1929]] despite the party finishing third nationally. The Liberal Democrats won every seat in the county in [[2005 United Kingdom general election|2005]], but lost seats to the Conservatives in [[2010 United Kingdom general election|2010]] before being wiped out in [[2015 United Kingdom general election|2015]]. The Conservatives won all six Cornish seats in 2015, [[2017 United Kingdom general election|2017]] and [[2019 United Kingdom general election|2019]]. Following expectation of a Conservative defeat at the [[2024 United Kingdom general election|2024 general election]], Cornwall was considered a three-party battleground.<ref>{{Cite web |date=2024-06-15 |title=Camborne and Redruth: Battle lines drawn in key Cornish seat |url=https://www.bbc.com/news/articles/crggdljwgrno |access-date=2024-06-16 |website=BBC News |language=en-GB}}</ref> The Conservatives lost all six seats and the county is currently represented by four Labour and two Liberal Democrat MPs.

Although Cornwall does not have a designated government department, in 2007 while [[Leader of the Opposition (United Kingdom)|Leader of the Opposition]] David Cameron created a Shadow Secretary of State for Cornwall. The position was not made into a formal UK Cabinet position when Cameron entered government following the [[2010 United Kingdom general election]]<ref>{{Cite news|url=http://news.bbc.co.uk/2/hi/uk_news/politics/7948984.stm|title='Fictional minister' prompts row|date=17 March 2009|via=BBC News }}</ref>
