Europeans vote on Sunday in an election expected to further dent traditional pro-EU parties and bolster the nationalist fringe in the European Parliament, putting a potential brake on collective action in economic and foreign policy. Polls opened at 7 a.m. (0400 GMT) in the east of the bloc and will finally close at 11 p.m. (2100 GMT) in Italy. Seven states have already voted, with 21 joining in on Sunday in what is the world`s biggest democratic exercise after India.
