[File:European Parliament composition by political groups election 2014.svg|thumb|Political groups of the European Parliament in the Louise Weiss building after the election 2014: ]] 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.
