Neither the Liberals nor the Christian Democrats have ruled out forming a government with Mr Wilders, who was last year banned from entering Britain for public safety reasons. The Home Office refused the politician entry on that grounds that he "would threaten community security and therefore public security". Mr Wilders had been invited to the House of Lords to show his 17-minute film, Fitna, which criticises the Koran as a "fascist book" and compares Islam to Nazism.
