Bradford West (UK Parliament constituency)
In 1981, however, Edward Lyons, the sitting Bradford West MP, joined the newly established Social Democratic Party, consequently losing the seat at the 1983 general election.This was attributed to the local party association selecting a Sikh, Marsha Singh to stand when the majority of the seat's population is Muslim.George Galloway of the Respect Party won the seat in the 2012 Bradford West by-election with 55.9% of the votes cast; his 30.9% majority was at the time the largest majority in the history of the modern constituency, but he lost the seat in 2015 to the new Labour candidate Naz Shah by a substantial (28.3%) margin.Despite Galloway's threats to contest the result, he neither launched a legal challenge nor stood again in 2017, in which Shah surpassed his record by winning a majority of 48.1%, the largest margin for a Bradford West MP in any incarnation of the seat.1885–1918: The Municipal Borough of Bradford wards of Allerton, Bolton, Great Horton, Heaton, and Manningham.
