Cohesion over time

Agreement Index per part-session, from 0 (evenly split) to 1 (all voted the same). A vote counts for a bloc when at least 10 of its members and a third of its seats voted; a gap is a period with fewer than 20 votes counted.

Cohesion of the groups per part-session, 20 Jan 2025 – 23 Jan 2025 to 14 Sept 2026 – 17 Sept 2026: Agreement Index from 0 (evenly split) to 1 (all voted the same).

20 Jan 2025 – 23 Jan 2025 → 14 Sept 2026 – 17 Sept 2026; each panel highlights one series, the others faint behind it.

Dashed: a period with fewer than 20 votes counted (no value) between two that have one.

Over the whole selection

Each group’s Agreement Index over every vote in the selection where enough of its members voted.

Cohesion: the Agreement Index (0–1) over the votes counted — votes where at least 10 members and a third of the seats voted; — : fewer than 20 such votes. Seats: members now. Order as the backend lists the blocs, not a ranking.

About these figures

What was counted, what was left out, and how.

  • 186 votes considered (all roll-call votes matching the filters; scope).
  • 9 of 42 decisions in the period had no final vote recorded by name (a show of hands or a count without names) and cannot be measured.
  • Cohesion is the Agreement Index: 1 when every voting member took the same position, 0 when the bloc split evenly three ways (method). A bloc counts on a vote only when at least 10 of its members and a third of its seats voted; the non-attached have no group cohesion.
  • Months are offered for all roll calls only, and a month needs at least 20 votes.
  • Each member is counted in the group they belonged to on the day of the vote (group at the date).
  • Roll calls are not a random sample: final votes on laws are recorded by name, most other roll calls because a group asked for it. A group’s line is inferred from its members’ votes; the Parliament publishes no whip.
  • Methods: Cohesion (Agreement Index) v1, Final votes and all roll calls v1, Group at the date of the vote v1.
  • Data as of 25 Sept 2026, 03:36 UTC (data stamp f37e5638cded, code 6d4005c55bde; what the stamp is).
