Cleveland was abolished in 1996 both as a county council and a non-metropolitan county, being succeeded by the unitary authorities of Hartlepool, Middlesbrough, Redcar and Cleveland, and Stockton-on-Tees. The constituency boundaries used up to the 2005 United Kingdom general election were drawn up when the county still existed. For the review which came into effect for the 2010 general election, the four authorities were considered separately, with Middlesbrough and Redcar and Cleveland being combined. For the 2023 Periodic Review of Westminster constituencies, coming into effect for the 2024 United Kingdom general election, the Boundary Commission for England considered the area comprising the Tees Valley Combined Authority, which also includes the unitary authority of Darlington, as a sub-region of the North East Region. For the purposes of this series of articles, the constituency of Darlington continues to be included in List of parliamentary constituencies in County Durham. The area is divided into 6 parliamentary constituencies – 3 borough constituencies and 3 county constituencies.

The commission also opted to rename Middlesbrough to Middlesbrough and Thornaby East, and rename Stockton South to Stockton West. The following seats resulted from the boundary review: Containing electoral wards in Hartlepool Containing electoral wards in Middlesbrough Containing electoral wards in Redcar and Cleveland Containing electoral wards in Stockton-on-Tees
