Dewsbury's seat dates back to 1868 and the electorate has usually given the winning MP marginal majorities which means it is a marginal seat. Labour MPs served the seat from 1935 until 1983 and again from 1987. In 2010 it was gained by Simon Reevell, a Conservative.

The constituency covers the towns of Dewsbury and Mirfield, and the surrounding areas.
In the 2010 redistribution, the constituency lost the Labour-leaning ward of Heckmondwike, but gained the Conservative-leaning wards of Denby Dale and Kirkburton.
The seat has a substantial Muslim population in the town of Dewsbury (particularly the Savile Town district), combined a few suburban and rural affluent parts such as Denby Dale, Mirfield, and Kirkburton. The town of Dewsbury itself is strongly Labour, and the remaining wards mostly Conservative. Overall the seat has close to national average income and several developments have desirable views as the upland town cuts into the Pennines. Relatively few people rely upon social housing, however the Dewsbury East ward contains a high proportion of social housing in the Chickenley estate, while Dewsbury South contains the Thornhill area, where the local school was the subject of the acclaimed Educating Yorkshire series. In the light of increasing concern over Muslim extremism, the Labour Party candidate Shahid Malik enjoyed a fairly large public media profile after his victory in 2005, with various TV appearances and interviews, strongly denouncing believers in and adherents of such views; however, this has also been a strong area for the British National Party, who obtained their highest vote in Britain (13.1%) in the 2005 general election, much of it taken at the Labour Party's expense. They have also had a substantial vote at local level, when in 2006 for the first time in the UK the BNP polled more votes than any other party standing. However, at the 2010 general election, the BNP's popularity in Dewsbury fell (despite a substantial nationwide rise in support for the party compared to five years previously) and they gained a mere 6% of the vote.[4]
Another General Election was due 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:
