AMSTERDAM (Reuters) - A new nationalist party led by a self-styled intellectual won two seats in Amsterdam in Dutch municipal elections seen as heralding the fragmentation of the country's far right.

The Forum for Democracy, which has touted what it calls Dutch cultural superiority and denounced the European Union, took 4.9 percent of the vote, good for two seats in the 45-member assembly of the largest Dutch city.

Although the party is participating only in Amsterdam, traditionally a liberal bulwark, national opinion polls show it is now the third most popular in the Netherlands.

An admirer of Donald Trump and Vladimir Putin, Forum for Democracy leader Thierry Baudet has siphoned voters from anti-Islam lawmaker Geert Wilders, who has been a fixture among European right-wing populists since 2006.

Baudet, a swaggering 35-year-old writer who entered the Dutch national Parliament after winning two seats in the March 2017 parliamentary election, echoing Trump's call to "drain the swamp", said his party would upend Amsterdam politics.

"We can bring so many things to light, we can throw spanners in the works, we'll turn over so many stones," he told ANP news.

Baudet has been called sexist and racist for various remarks he has made, including saying last year that women "generally excel less in many occupations and lack ambition" and that Dutch "people are being homeopathically diluted by mixing them with all the peoples of the world".

But his words have struck a chord with some and the Forum for Democracy has drawn adherents of Wilders' Freedom Party, which has lost more than a third of its popular support and is now polling in seventh place nationally.

Wilders' party, currently the second largest in parliament, has struggled to find suitable candidates to compete in the local elections.

Anti-migrant sentiment played an important role in the election campaign, though which housing shortages and rapidly rising rents were also central issues.
