Non-Inscrits (abbreviated NI; , abbreviated NA) are Members of the European Parliament (MEP) who do not sit in one of the recognised political groups.
These MEPs may be members of a national party, or of a European political party, but for a political grouping to be formed in the European Parliament there need to be 25 MEPs from seven different states. Being part of a group grants access to state funds and committee seats, but the group members must be ideologically tied. Groups of convenience, such as the Technical Group of Independents, previously existed, but are no longer allowed, and the minimum requirements for group formation have been raised, forcing less numerous elements to sit as NIs.
Political ideologies displayed by the Non-Inscrits range from communism and social liberalism to populism, conservatism, national conservatism, nationalism and neo-nazism. As of 2015 however, the Non-Inscrits mostly consist of far-right parties.
In the 6th European Parliament 23 right-wing NIs briefly formed the Identity, Tradition, Sovereignty group at the start of 2007, but it collapsed on 14 November 2007 due to internal disagreements.
