Revealed ideal point estimates of MEPs in the three European Parliaments (a) the first elected European Parliament, 1979–1984, (b) the third elected European Parliament, 1989–1994, (c) the fifth elected European Parliament, 1999–2004. These figures are the result of applying the W-NOMINATE geometric scaling metric to all the roll-call votes in each of these parliaments. Each dot is the estimated location of an MEP on the two main dimensions of voting in a particular European Parliament. The method is an inductive scaling technique, and as such does not provide an a priori substantive meaning of the dimensions. The colours in the figures indicate the political groups: red dots, the social democrats; blue dots, the conservatives and Christian democrats; yellow dots, the liberals; dark red dots, the radical left; light blue dots, the British conservatives and their allies (who then joined the EPP); navy blue dots, the national conservatives; green dots, the greens and regionalists; purple dots, the extreme right; pink dots, the anti-Europeans; grey dots, the non-attached MEPs.
