An exit poll for Dutch Public Service broadcaster NOS 1 indicates a big win for the anti-immigrant Party of Freedom, led by Geert Wilders, in the Dutch European Parliament elections.
Turnout is projected at 40%, marginally higher than the 39% in 2004.
According to the exit poll the ruling Christian Democrat party of Prime minster Jan Peter Balkenende will remain the biggest party, with 20.3% of the vote, giving it five of the 25 Dutch seats.
The Party of Freedom (PVV) comes in second, with 14.8%, giving them four seats, their first representation in the European Parliament.
The PVV first contested an election in 2006, when they won nine of the 150 seats in the lower house of the Dutch Parliament.
The party platform is strongly anti-Muslim, anti-immigrant, and anti-EU.
Mr Wilders is under constant police protection after Muslim extremists threatened to kill him.
He was recently banned from Britain, and has released a controversial film called Fitna, which criticises the Koran, which Mr Wilders believes should be banned.
In 2005 he was the leading figure in the Dutch campaign against the EU constitutional Treaty.
