Among many classes of local labourers saw organised Labour Party support, in Trade Unions, party clubs and civic society. Progression in the party's polling was heightened from the early 1920s when the seat joined many wrested from the Liberal Party, enabling the formation of the first Labour government. By length of tenure and in great majorities a safe seat status emerged for Labour (on the basis of these standard criteria) in the 1950s and 1960s. In the 1980s general elections Labour's Mansfield candidates came closer to losing to Conservatives. At the 1983 election, Labour held the seat by just over 2,000 votes – at the following, in 1987, 56 votes. That election was set against the background of the party HQ-backed miners' strike of 1984, not supported by the majority of miners in Nottinghamshire.
