"Elections to the European Parliament take place every five years by universal adult suffrage. 751 MEPs (Members of the European Parliament) 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 are still taking place through national election campaigns, advertising national delegates from national parties."

"There are six types of elections in the United Kingdom: United Kingdom general elections, elections to devolved parliaments and assemblies, elections to the European Parliament, local elections, mayoral elections and Police and Crime Commissioner elections. Elections are held on Election Day, which is conventionally a Thursday. General elections do not have fixed dates, but must be called within five years of the opening of parliament following the last election. Other elections are held on fixed dates, though in the case of the devolved assemblies and parliaments early elections can occur in certain situations. Currently, six electoral systems are used: the single member plurality system (First Past the Post), the multi member plurality system, party list PR, the single transferable vote, the Additional Member System and the Supplementary Vote.
Elections are administered locally: in each lower-tier local authority, the actual polling procedure is run by the Returning Officer and the compiling and maintenance of the electoral roll by the Electoral Registration Officer (except in Northern Ireland, where the Electoral Office for Northern Ireland assumes both responsibilities). The Electoral Commission only sets standards for and issues guidelines to Returning Officers and Electoral Registration Officers, but is responsible for nationwide electoral administration (such as the registration of political parties and directing the administration of national referendums)."
