The anti-Islam party PVV asks journalists for their personal data, including their citizen service number (BSN), when they apply to attend a press conference, news agency GPD reports on Thursday.

Asking for someone’s BSN number is against the law, the GPD quotes privacy experts as saying. And for a political party to do so is entirely unacceptable.
The PVV says they ask for the information at the request of the national terrorism coordinator and the royal and diplomatic security service (DKDB) which is responsible for the security of party leader Geert Wilders.
‘We need to know who’s at a press conference and the BSN is the easiest way of finding out,’ a security service spokesman told the GPD.
