The ceremonial county of Tyne and Wear is divided into 13 parliamentary constituencies, including 2 cross-county boundary seats with Northumberland and one with Durham, of which 9 are borough constituencies and 4 county constituencies.
See 2023 review of Westminster constituencies for further details.
For the 2023 review of Westminster constituencies, which redrew the constituency map ahead of the 2024 general election, the Boundary Commission for England opted to combine Newcastle upon Tyne and North Tyneside with Northumberland as a sub-region of the North East Region, with the creation of two cross-county boundary constituencies comprising an expanded Hexham seat and a new seat named Cramlington and Killingworth. Gateshead, South Tyneside and Sunderland would be combined with County Durham, resulting in another cross-county boundary constituency, named Blaydon and Consett. The constituencies names of Blaydon, Gateshead, Jarrow, North Tyneside, Newcastle upon Tyne Central, Newcastle upon Tyne East, and Washington and Sunderland West were abolished, and new or re-established constituency names of Gateshead Central and Whickham, Jarrow and Gateshead East, Newcastle upon Tyne Central and West, Newcastle upon Tyne East and Wallsend, and Washington and Gateshead South created.
The following seats resulted from the boundary review:
Containing electoral wards from Gateshead
Containing electoral wards from Newcastle upon Tyne
Containing electoral wards from North Tyneside
Containing electoral wards from South Tyneside
Containing electoral wards from Sunderland
Under the fifth periodic review of Westminster constituencies, the Boundary Commission for England decided to reduce the number of seats in Tyne and Wear from 13 to 12, leading to significant changes. The constituencies of Gateshead East and Washington West, Houghton and Washington East, Sunderland North, Sunderland South, and Tyne Bridge were abolished and replaced with Gateshead, Houghton and Sunderland South, Sunderland Central, and Washington and Sunderland West. Newcastle upon Tyne East and Wallsend became Newcastle upon Tyne East.
