The populist right-wing PVV party, known for its anti-immigration and Eurosceptic stances, won by far the most seats in the Dutch House of Representatives, 37, and got the largest share of the popular vote, 23.5 per cent, as well in last night’s special election. Party leader Geert Wilders is a long-time ally of Prime Minister Viktor Orbán of Hungary.
