The political groups of the European Parliament are the parliamentary groups of the European Parliament. The European Parliament is unique among supranational assemblies in that its members (MEPs) organise themselves into ideological groups as in traditional national legislatures. The members of other supranational assemblies form national groups. The political groups of the European Parliament are usually the formal representation of a European political party in the Parliament. In other cases, they are political coalitions of a number of European parties, national parties, and independent politicians.
