The Dutch right-wing populist politician Geert Wilders has led his supporters in an anti-Moroccan chant.

At a party meeting Wednesday evening in The Hague, where his Freedom Party is set to win the most votes in municipal elections, Wilders asked supporters whether they wanted "more or fewer" Moroccans in the Netherlands.

His supporters chanted back: "Fewer! Fewer! Fewer!" before breaking into applause.

"Good, we're going to take care of that," Wilders said.

Wilders' party is the fourth-largest in Parliament but leads in national opinion polls. His rise to popularity in the Netherlands over the past decade came amid a surge of anti-immigrant sentiment in a country once famed for its tolerance. In 2011 he was acquitted of hate speech charges for anti-Muslim remarks.
