The London Borough of Islington was divided into three constituencies. Islington North was defined as comprising seven wards: Highview, Hillmarton, Hillrise, Junction, Parkway, St. George's and Station. 1983–1997 In 1983 the parliamentary representation of Islington was reduced to two constituencies. The new, enlarged, Islington North was formed from ten wards of the borough as they existed in February 1983. These were Gillespie, Highbury, Highview, Hillrise, Junction, Mildmay, Quadrant, St. George's, Sussex and Tollington wards. 1997–2010 In 1997 there were only slight boundary changes, with the constituency defined as the same ten wards with their boundaries as they existed on 1 June 1994. Since 2010 The seat, which is the smallest constituency in the UK by area, covers the northern half of the London Borough of Islington, which includes the areas of Holloway, Highbury, Tufnell Park, Upper Holloway and Archway. The constituency now comprises eight electoral wards: Finsbury Park, Highbury East, Highbury West, Hillrise, Junction, Mildmay, St. George's and Tollington. These boundaries have been considerably changed since 1970, when Islington returned three MPs and shared another with Hackney. This reflects the depopulation of central London on a lowering of adult occupancy of households and the local authority has replaced tower blocks. The core of the constituency was the area north of Seven Sisters Road and Camden Road. At , it is the smallest UK Parliamentary constituency. At the Fifth Periodic Review of Westminster constituencies begun in 2012 the seat was approximately 1,300 electors below the electoral quota and the highest concentration of elector density nationally. The criteria of successive reviews emphasise equal electorates as well as restricting seats to one or, if unavoidable, two local authority areas.

This highlighted the importance of the local Irish community, the poor local housing conditions (the opening line talks of "a crowded, crumbling constituency") and the relatively low turn-outs at previous elections. The film is now available through British Pathé Archive. Michael O'Halloran,
