European Parliament coalitions across the ideological spectrum

Each row is a coalition type drawn as a fold across the eight groups (Left→ESN). Blue = the pro-EU / centre / winning side; orange = the opposing flanks. Vertical breaks mark the cutting lines. Pick a policy area to re-weight how often each coalition forms.

Reading the strips: a single break is a left–right cut; a blue centre flanked by orange on both ends is a Centre-vs-Periphery vote (the Eurosceptic left folding onto the radical right); a blue centre-right block with orange on the left and at the far-right edge is a Centre-Right-plus coalition. "Other / realignment" pools votes with no single fold geometry.

Cohesion and winning side

Group cohesion scores run from 0 (if the MEPs in a group split 50-50 in all votes) to 100 (if all MEPs in a group voted the same way in all votes).

Interactive scatter plot of European Parliament political groups showing party cohesion against how often each group is on the winning side, selectable by policy area, with a companion chart showing winning-side rates across the ideological spectrum.

How loyal are national delegations to their political group?

Each dot is a national delegation (a member state’s MEPs within one group, minimum 3 MEPs; 81 delegations), positioned by the share of votes in which its plurality position matched its group’s. Dot size = number of MEPs. Switch policy areas to watch delegations break ranks; click a dot to pin its full policy profile.
