Bontes represented the Party for Freedom (PVV) until 2013, and focused on matters of the European Union, civil law, security, police and foreign policy (Africa, Middle and South America). From 2009 to 2010, he was an MEP for the PVV. In October 2013, after Bontes talked to the media about his being disappointed with the methods of the PVV, the party's parliamentary group expelled him.
