This seat was created by the Redistribution of Seats Act 1885, since which it has been won at elections by candidates from only two parties. For nineteen of the years between 1885 and 1950, North Dorset was represented by Liberals, and at all other times since 1885 it has been represented by Conservatives. It is historically one of Labour's weakest seats in the country - for example, it gave the party its lowest vote share out of all the seats it contested in 1950 and 1951.
