Within individual countries there is usually a good understanding of how parties differ from one another on economic issues, but how do parties in different European countries compare? Would Angela Merkel’s Christian Democrats lie to the right of Mariano Rajoy’s People’s Party in Spain? Is the British Labour Party to the left of other centre-left parties in Europe? Based on data from expert surveys, Ryan Bakker, Seth Jolly and Jonathan Polk map the left/right positions of political parties from 14 eastern and western European countries. They write that while this comparison gives a good indication of party competition across Europe, future research will also allow for European parties to be compared on non-economic dimensions and with parties in other parts of the world such as North America.
