National Delegation Alignment
delegation-loyaltyv1.0Published: 2026-05-01Current versionHow often a MEP votes with the majority position of their national delegation (MEPs from the same country).
Formula
delegation_loyalty = votes_matching_delegation_majority / eligible_expressed_votesIncluded in the calculation
Votes where the MEP cast For, Against or Abstain AND the national delegation had a clear majority position.
Excluded from the calculation
Votes where the MEP was absent. Votes where the national delegation had no clear majority (delegation split). Votes from before the MEP joined.
Limitations
National delegations include MEPs from different political groups, so a national majority emerges from cross-group consensus. A high alignment can indicate strong national interest on a topic; a low one can indicate the MEP follows their European group over their national peers.
Implementation: open source under MIT. The calculation logic lives in the project repository under pipelines/.
