A European political party (formally, a political party at European level; informally a Europarty) is a type of political party organisation operating transnationally in Europe and in the institutions of the European Union. They are regulated and funded by the European Union and are usually made up of national parties, not individuals. Europarties have the exclusive right to campaign during the European elections and express themselves within the European Parliament by their affiliated political groups and their MEPs. Europarties, through coordination meetings with their affiliated heads of state and government, influence the decision-making process of the European Council. Europarties also work closely and co-ordinate with their affiliated members of the European Commission and, according to the Lisbon Treaty the Europarty that wins the European elections has the right to nominate to the European Council its candidate for President of the European Commission.
