Local roots and rebellion: Constituency connections and legislative behaviour of British MPs, 2010–21

Abstract This study explores the relationship between the local roots of Westminster MPs and parliamentary party discipline, a central principle of the British system of responsible party government. While recently the local base of MPs has attracted increasing academic attention, only little effort has been put into investigating how this might influence the political behaviour of parliamentarians. In order to do so, this study utilizes a comprehensive database on the local base of British parliamentarians, which includes data on all Westminster MPs from 2010 to 2021, supplemented with information on parliamentary dissent. Contrary to theoretical assumptions and existing international studies, localness is shown to have no positive influence on MPs propensity for parliamentary rebellion. This suggests that the increasing recruitment of local candidates does not challenge the traditional functionality of the responsible party system of government, yet nor should localness be seen as a panacea for the perceived representational deficits of British democracy.
