The article identifies and analyses the patterns of political representation of the regions of Slovakia in terms of the functioning of the proportional electoral system with only one electoral district for the whole country. In this system, the representation of the region of the capital city, which is several times higher than the representation of other regions, dominates significantly. At the same time, a Western-Eastern gradient was identified in the regional political representation pattern, where the more economically developed western part of the country is politically much better represented than the peripheral regions of eastern Slovakia. The impact of a single electoral district is relevant in the geographical context as well as in significant centralization of the political power within the party-political system.
