Support for the anti-Islamic Freedom Party of Dutch populist Geert Wilders has jumped to its highest level in more than a year after the militants attacks in Paris.If elections were held now, Wilders's party would be the single largest in the Netherlands, with 31 seats in the 150-member parliament, more than twice as many as it won in the last elections, according to a Sunday poll. The governing Liberal and Labour parties, damaged by persistent sluggish growth, would have just 28 seats between them, compared to the 79 they held after the 2012 elections. The Freedom Party was polling 30 seats just prior to the Jan. 7-9 Paris attacks, in which 17 people including journalists and policemen were killed by three Islamist gunmen who were later shot dead by French special forces.In the wake of that bloodshed, Wilders said that the West was "at war" with Islam and he called for tough measures against it. "If we don't do anything, it will happen here," he was quoted by the newspaper Het Parool as saying. More than 80 percent of respondents to the De Hond poll said people who left the Netherlands to wage jihad (holy war) in Syria should lose their Dutch citizenship and those returning from fighting in Syria or Iraq should face lengthy jail terms.The attack on the French satirical newspaper Charlie Hebdo had particular resonance in the Netherlands. Twelve years ago, Dutch filmmaker Theo van Gogh, known for making anti-Islam remarks that were designed to offend, was stabbed to death by an Islamic radical as he cycled down an Amsterdam street. Wilders, who has described Islam as a "lie" and the prophet Muhammad as a "criminal", has lived in hiding and under 24-hour armed guard since van Gogh's murder in 2004. He is currently facing prosecution over remarks he made at an election rally last year, when he appeared to call for "fewer Moroccans" in the city of The Hague, and later referred in a television interview to Moroccan scum.
