Voting has begun in Britain and the Netherlands for European Parliament elections in which Euroskeptic parties stand to be the likely beneficiaries of a disillusioned and apathetic electorate.

Some 400 million Europeans are eligible to vote, with national polls being held Thursday through Sunday.

More than 16,000 candidates from 953 parties or lists — from greens to feminists to the far-right — are vying for the legislature's 751 seats.

Many voters are increasingly skeptical of efforts to unite the continent into an economic and political superpower.

In Britain, the anti-EU U.K. Independence Party could gain the largest share of votes.

Prominent Euroskeptic Geert Wilders, leader of the Dutch Party for Freedom, said "a vote for my party is a vote for national sovereignty, for less immigration, for less Brussels."
