Elections for the European Parliament take place every five years in the EU member states. Each country has its own voting system, but they must use a form of proportional representation and cannot have election thresholds over 5%. Most countries use party list PR across the entire state, but some like Belgium and the UK divide into constituencies. Europarties campaign EU-wide and must put forward a candidate for European Commission President. Voter turnout has declined in each election as some see it as a way to punish national governments. Reforms are being considered to make the elections more pan-European and increase voter engagement.
