The investigation into the anti-Islam Wilders follows a request for judicial assistance from Vienna, after a March 2015 address by Wilders at a gathering of Austria’s far right Freedom Party (FPÖ).
Prominent far-right activists from Europe who were planning to attend an anti-Muslim rally in Birmingham have been detained at airports hours before they were due to speak.
Jacek Międlar, 28, an antisemitic priest, and his fellow activist Piotr Rybak were among three Polish nationals stopped on Saturday morning, according to Polish media and social media posts. They were due to speak at the rally organised by far-right group Britain First. At around the same time, a Dutch national Edwin Wagensveld, who heads his country’s branch of the Islamophobic movement Pegida, was held at Birmingham airport, Britain First said.
