text: # List of parliamentary constituencies in County Durham
  
  The unitary authorities of Durham and Borough of Darlington are combined for the purpose of parliamentary constituency boundaries, being divided into 7 parliamentary constituencies– 1 borough constituency and 6 county constituencies. Since the 2019 general election, 4 parliamentary seats are controlled by the Conservative Party and 3 by the Labour Party. Between 1992 and 2019, all 7 seats were held by the Labour Party. With the exception of Darlington, all seats in the current ceremonial county or their predecessors had returned Labour MPs since 1935.

  ## 2010 boundary changes
  
  Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to retain Durham's constituencies for the 2010 election, making minor changes to realign constituency boundaries with the boundaries of current local government wards.
  
  | Name | Boundaries 1997-2010 | Boundaries 2010–present |
  | - | - | - |
  | Bishop Auckland CC City of Durham CC Darlington BC Easington CC North Durham CC North West Durham CC Sedgefield CC | Parliamentary constituencies in Durham | Proposed Revision |
  
  ## 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 proposals were published on 28 June 2023.
  
  The commission has proposed that the unitary authority of County Durham be combined with the Tyne and Wear boroughs of Gateshead, South Tyneside and Sunderland as a sub-region of the North East Region, with the creation of a cross-county boundary constituency named Blaydon and Consett, resulting in the abolition of North West Durham. It is proposed that the reconfigured Sedgefield constituency is renamed Newton Aycliffe and Spennymoor. Darlington would be included in a Tees Valley sub-division.
  
  The following seats are proposed:
  
  Containing electoral wards in Darlington
  
  * Darlington
  * Stockton West (part also in Stockton-on-Tees)
  
  Containing electoral wards in County Durham
  
  * Bishop Auckland
  * Blaydon and Consett (part also in Gateshead in Tyne and Wear)
  * City of Durham
  * Easington
  * Newton Aycliffe and Spennymoor
  * North Durham
