Academic research has been carried out into UKIP. In 2016, it was noted that most of this had focused on examining the party's electoral support base, its consequences for other parties, and the possibilities and prospects of a referendum on continued EU membership, with little having focused on an examination of the party's policies. Two currents have emerged among those seeking to interpret UKIP: the first, and generally older, current views them as a manifestation of Britain's strong Eurosceptic movement, while the second seeks to explain their position in the British parliamentary system while drawing upon the comparative literature on right-wing populist parties elsewhere in Europe.
