The seat was created for the 1885 general election as one of two divisions of the county which succeeded Bedfordshire county constituency and was formally known as the Southern or Luton Division of Bedfordshire. The constituency adjoined the Northern or Biggleswade Division to the north of the county until 1918.
From the 1910s onwards the town of Luton and contiguous suburbs expanded, as recorded at the census in each decade, resulting in expanding electorates. This resulted in territory loss to newly formed seats in 1918 and 1950 and further population growth (coupled with a programme of new housing principally under the New Towns Act 1946) justified abolition and division into East and West seats in 1974.
Political summary
Before 1945
The seat was Liberal-candidate held for 40 of the 46 years before 1931. The remaining six years had been won by Conservative and Unionist Party candidates, running under the emphasis of the party as 'Unionist'. In 1931, the sitting Liberal MP, Leslie Burgin, joined the Liberal Nationals (later the National Liberal Party).
After 1945
In the election landslide of 1945, the seat was won by the Labour Party, but recaptured at the next election by Charles Hill who served as a National Liberal, in coalition with the Conservatives, from 1950 until 1963, when he was made a life peer (Baron Hill of Luton). The resulting by-election was won by Labour which held it until 1970 when it was taken by the Conservative Party until the seat was abolished for the February 1974 general election.
Electorate size
The electorate rose through house-building from a relatively modest 37,051 in 1918 to an over-sized (malapportioned) 95,227 in 1945.[1]
The constituency was created as the Southern or Luton Division of Bedfordshire under the Redistribution of Seats Act 1885, when the two-member Parliamentary County of Bedfordshire was divided into the two single-member constituencies of Biggleswade and Luton.
Northern and western parts of the Division, including Leighton Buzzard and surrounding rural areas, were transferred to the new Mid Bedfordshire Division.
