The seat saw a first winning candidate from the Labour Party relatively early in its history, in 1923. The seat alternated between the two largest modern parties eight times between 1923 and 1979.
In more recent history, reflecting the growing population of Telford and the rich iron smelting, railway and mining industries as major historic employers in the area, the seat was more Labour-leaning than the national average but still marginal, being represented by a Conservative for the first eight years of the Thatcher ministry and then (from 1987) returning a Labour member, who was moved to a new Telford seat in 1997, and another Labour member until 2005, followed by the present Conservative who was elected that year. The current Conservative majority is 18,726 votes.
Anthony Trafford (Conservative) went on after serving as MP to serve as a health minister, from the House of Lords in 1989.
Bruce Grocott (Labour) went on, after serving as MP for the newly created neighbouring seat from 1997 to 2001, to serve as the Government's Chief Whip in the House of Lords for six years.

When originally constituted, the constituency, with a population of 71,352, was the largest division of Shropshire created in the 1918 boundary changes.[2]
In the Third Periodical Review of the Boundary Commission, which took effect for the 1983 general election, the constituency was redefined after major local government changes. This redefinition resulted in a quarter of the electorate being removed to Shropshire North and Ludlow.[3]
Parliament approved major boundary changes which took effect at the 1997 general election, which created a new constituency containing and named after the town of Telford, before which Telford had been one of the largest elements of The Wrekin. The new Telford constituency took 62.9% of the electorate of The Wrekin leaving the remaining 37.1% to constitute a revised constituency of The Wrekin that incorporated areas previously within Shropshire North and Ludlow from two sides.[4]
The area almost encircles Telford, a 'New Town', encompassing much of the rural parts of the Telford and Wrekin borough, in which most of the constituency is. Its major settlements include: Wellington, Newport and Shifnal, as well as the suburban northern reaches of Telford (including Donnington). A small but significant area relates to the former Bridgnorth local government district (now part of the unitary Shropshire) and contains RAF Cosford and a number of commuter villages along the M54 motorway: the civil parishes of Sheriffhales, Shifnal, Tong, Boscobel, Albrighton, Donington and Boningale make up the non-Telford and The Wrekin-administered portion. Boundary changes to realign the constituency boundaries to fit with the borough's most recent ward revisions resulted in the removal of Ketley (to the constituency of Telford) for the 2010 general election.[5]
The County of Shropshire electoral divisions of: Albrighton; Cheswardine; Hodnet; Shifnal North; Shifnal South and Cosford.
The Borough of Telford and Wrekin wards of: Admaston & Bratton; Apley Castle; Arleston; Church Aston & Lilleshall; College; Donnington; Dothill; Edgmond & Ercall Magna; Ercall; Hadley & Leegomery; Haygate; Muxton; Newport North & West; Newport South & East; Park; Shawbirch; Wrockwardine.[6]
The wards of Hodnet and Cheswardine will be added from the North Shropshire constituency and there will be a small adjustment in the Telford and Wrekin Borough.
In its initial proposals, the boundary commission put forward the new name for the constituency of "Wellington and Newport"; this met with opposition locally and was dropped in the revised proposals.[7]
Following a local government boundary review in Telford and Wrekin which came into effect in May 2023[8][9], the constituency will now comprise the following from the next general election:

Unemployment claimants were in November 2012 lower than the national average of 3.8%, at 3.1% of the population based on a statistical compilation by The Guardian.[11]
Note: although The Wrekin was a Labour-held seat in the previous Parliament, boundary changes removed many Labour-leaning areas that now fall in the neighbouring seat of Telford, which Bruce Grocott decided to contest in 1997 instead of the new Wrekin seat. These changes made it notionally a Conservative seat, hence this is a gain rather than a hold.
Another General Election was required to take place before the end of 1940. The political parties had been making preparations for an election to take place from 1939 and by the end of this year, the following candidates had been selected;
