The seat dates back to 1918 at which time it was at an extremity of the largely urbanised London postal district outside of the County of London (1889–1965). It was a railway commuter town core outweighed by businesses beside the River Lea engaged in manufacturing, storage, distribution, and construction industries, among others.[4] Population and housing were significantly less before the middle of the 19th century.[5]
The seat was won by successive Labour party candidates since 1935 until narrowly gained by a Conservative at the 1983 United Kingdom general election. The latter's majority increased in 1987 then reduced to a marginal majority in 1992. After 1997 a trend of increased Labour majorities developed. Osamor's majority of 2015, 37.3%, made it the 43rd-safest Labour seat in ranking in 2015.[6] Likewise, save for a Conservative-leaning ward, Bush Hill Park, Edmonton's other wards usually elect Labour Party councillors since 1997.[citation needed]
