The rightwing Swiss People’s Party has accused the authorities of tolerating attacks on its offices and its representatives following Sunday’s vote on deporting foreign criminals.
At a news conference on Wednesday senior party officials said the assaults were a threat to freedom of opinion and the right of free assembly.
Last Sunday protestors took to the streets of Zurich smashing up shop windows and breaking the entrance of a hotel in Bern where the initiative committee met. Party offices were also occupied or vandalised.
The People’s Party also claimed that the authorities did not help find a venue for next Saturday’s assembly of delegates in western Switzerland.
The city of Lausanne and the local university both refused to host the delegates over threats of attacks by opponents.
