The parliamentary borough of Finsbury was a constituency of the House of Commons of the UK Parliament from 1832 to 1885, and from 1918 to 1950. The constituency was first created in 1832 as one of seven two-seat "metropolis" parliamentary boroughs (five in southeast Middlesex and two in northeast Surrey) other than the two which already existed: Westminster and the City of London; the latter until 1885 retained an exceptional four seats. Finsbury was directly north of the City of London and was smaller than the Finsbury division of the Ossulstone hundred but took in land of Holborn division (hundred division) to its southwest in pre-introduction changes by Boundary Commissioners. It included Finsbury, Holborn, Moorfields, Clerkenwell, Islington, Stoke Newington and historic St Pancras (later mainly known as Camden Town). The 1918 constituency corresponded to the smaller Metropolitan Borough of Finsbury (Finsbury, Moorfields, Clerkenwell, and St Luke's, Islington); it was a seat, thus electing a single member, fulfilling a longstanding aim of Chartism which underscored the 1832 reforms.
It was originally proposed that the constituency would comprise the entire Finsbury Division and a number of adjoining parishes in the Holborn Division of Ossulstone, one of the hundreds of Middlesex. The commissioners appointed under the Boundaries Act decided to exclude the northern part of the Finsbury Division, which extended as far as Friern Barnet, some nine miles from London and a largely rural area. They could find no natural boundary to separate "the Rural from the Town District" and suggested that the dividing line should run through the northern section of Islington, following limits of relatively recently founded Church of England parishes. The seat as eventually created included the whole of Islington, however.[1]
The parliamentary borough was defined in Schedule O of the Boundaries Act as:
The Redistribution of Seats Act 1885 divided the constituency, by then highly populated, into seven new single member constituencies. Four were divisions of a new Parliamentary Borough of Islington; while the Finsbury Parliamentary Borough was divided into three, named Central Division, East Division and Holborn Division.
Another general election was required to take place before the end of 1940. The political parties had been making preparations for an election to take place and by the Autumn of 1939, the following candidates had been selected;
