Mr Wilders, the leader of the anti-Islamist Party for Freedom (PVV), is taking on Mr Rutte, from the Party for Freedom and Democracy (VVD), in the knife-edge election race.
The blonde populist has already cast his vote in the election after a fiery election campaign in which he pledged to shut the country's borders, ban the Koran and close mosques.
The election is overshadowed by spat with Turkey after Turkish ministers were banned from speaking in Rotterdam as part of a row over Ankara’s political campaigning among emigres.
If Wilders wins the election, it is seen as being another nail in the coffin for the European Union (EU). Many Dutch are angry over Muslim immigration and this election could be a major statement by the people of the Netherlands on that issue.
