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.
The seat saw a first winning candidate from the Labour Party relatively early in the country's 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 went on to serve a new seat created to serve Telford in 1997, and another Labour member until 2005, followed by the present Conservative who was elected that year. The present majority is over 10,000 votes.

When originally constituted, the constituency, with a population of 71,352, was the largest division of Shropshire created in the 1918 boundary changes.
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.
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.
Future proposals: Under constituency boundary proposals announced in September 2016, ahead of the next general election, this constituency is proposed to lose the Donnington and Hadley and Leegomery wards to Telford constituency, while the remainder will be merged into a new seat called Bridgnorth, Wellington and the Wrekin.
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;
