Elections to the European Parliament take place every five years by
universal adult suffrage. 751
MEPs are elected to the
European Parliament, which has been directly elected since 1979. No other EU institution is directly elected, with the
Council of the European Union and the
European Council being only indirectly legitimated through national elections. While
Europarties have the right to campaign EU-wide for the European elections, campaigns still take place through national election campaigns, advertising national delegates from national parties.
