text: # List of parliamentary constituencies in Cornwall
  
  The ceremonial county of Cornwall, which includes the Isles of Scilly, is divided into six parliamentary constituencies. They are all county constituencies.
  
  ## Parliamentary history of Cornwall
  
  All six parliamentary seats are currently held by Conservatives, having came from holding no seats in 1997, 2001 and 2005, to gaining three of the six from the Liberal Democrats in 2010, to gaining the remaining three to hold all six Cornish seats in 2015. All six MPs were re-elected in 2017. In that election, several previous Liberal Democrat candidates, including previous MPs Andrew George and Steve Gilbert re-stood in their old seats, but failed to be re-elected. In all six seats, the Labour vote surged, pushing the Liberals into third place in four of the six seats. In the 2019 election, Labour retained their position as the second-placed party in most of the Cornish seats, holding their vote up far better in the region than elsewhere in the country. The last Labour MP for a Cornish constituency was Candy Atherton, who held the seat of Falmouth and Camborne between 1997 and 2005.

  ## 2010 boundary review
  
  Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to increase the number of seats which covered Cornwall from 5 to 6. Falmouth and Camborne, and Truro and St Austell were abolished and replaced by Camborne and Redruth, St Austell and Newquay, and Truro and Falmouth.
  
  | Former name | Boundaries 1997–2010 | Current name | Boundaries 2010–present |
  | - | - | - | - |
  | Falmouth and Camborne CC North Cornwall CC South East Cornwall CC St Ives CC Truro and St Austell CC | Parliamentary constituencies in Cornwall | Camborne and Redruth CC North Cornwall CC South East Cornwall CC St Austell and Newquay CC St Ives CC Truro and Falmouth CC | Proposed Revised constituencies in Cornwall |
  
  ## Proposed boundary changes
  
  See 2023 Periodic Review of Westminster constituencies for further details.
  
  Following the abandonment of the Sixth Periodic Review (the 2018 review), the Boundary Commission for England formally launched the 2023 Review on 5 January 2021. Initial proposals were published on 8 June 2021 and, following two periods of public consultation, revised proposals were published on 8 November 2022. The final recommendations were submitted to the Speaker of the House of Commons and then published on 28 June 2023.
  
  When the final recommendations come into effect at the next general election, the six existing parliamentary constituencies in Cornwall are to be retained with the same names and relatively minor alterations compared to other parts of the country.
