Territorial representation, the representation of local entities in the Westminster Parliament, lies at the heart of British democracy. In the recent academic debate, it has been asked whether local representation also needs a local representative and which specific characteristics would constitute ‘localness’ in this context. Investigating the biographies of 1108 Westminster MPs between 2010 and 2019 and exploring different dimensions of local base, this study examines the extent to which the demand for a local representative is actually fulfilled in the British Parliament. We discover a slow yet stable increase in the descriptive representation of the local (DRL) over time as well as notable variations across party and regions, especially among the constituent nations of the United Kingdom. Applying a genuine territorial perspective to our results, we link the detected DRL increase to the general territorialisation of politics in the UK. The fact that the political divergence of its constituent parts affects even the implementation of a core principle of British democracy is finally depicted as another indicator of the deep territorial divisions pervading British politics.
