Each country decides how it will conduct its elections, but it must guarantee gender equality and a secret ballot. EU elections are held on the basis of proportional representation.
Seats are allocated based on the population of each Member State. Just over a third of MEPs are women. MEPs are grouped by political affinity, not nationality.
Some of the powers of the European Parliament:
approves the Commission and its President
has the right to pass a vote of confidence
has the right to question Commissioners
