The Nordic Green Left Alliance is a transnational federation of parties, not a pan-European political party per se, but it articulates a broadly uniform ideology and its membership is exclusive to it. As such, it is treated akin to one here.
The European Democrats are an informal body who only express themselves as a subgroup in the European Parliament. They likewise enjoy a relative ideological uniformity and membership exclusive from the other organizations. They are also treated like the other pan-European political organizations in the below chart.
Only parties represented in national parliaments or the European Parliament are included in the below chart, while independents have been omitted. Please note that great ideological diversity can be found in most pan-European organizations, and individual country rows may not correspond with the heuristic left-right spectrum commonly used within its own political discourse.
Standalone parties with representation in the Parliamentary Assembly of the Council of Europe (but not the European Parliament) are coloured by the parliamentary group in which they sit in the former. These are:
EPP
PES
ALDE
EDG
EUL
Non-Attached
The "Standalone parties of the political centre" column includes some single-interest parties that claim to draw support from all across the spectrum.
† indicates the party has observer status within transnational organization
National parties are sorted by the alignment adopted by the party's leadership; in some cases MEPs have chosen to sit in different groups within the EP.
