Lord Pearson of Rannoch, a UKIP member of the House of Lords (the upper chamber of the British Parliament), invited Wilders to a February 12, 2009 showing of Fitna in the Palace of Westminster.[56] Two days before the showing, the Home Secretary, Jacqui Smith, banned Wilders from entering the territory of the United Kingdom, labelling him an "undesirable person".[56] A Home Office spokesperson elaborated that "The Government opposes extremism in all its forms... and that was the driving force behind tighter rules on exclusions for unacceptable behaviour that the Home Secretary announced in October last year."[38]
Wilders defied the ban and entered via Heathrow airport on the 12th, accompanied by TV crews.[6] He was quickly detained by UK Border Patrol officials and sent back on one of the next flights to the Netherlands.[6] He called Prime Minister Gordon Brown "the biggest coward in Europe" and remarked that "Of course I will come back."[6] Lord Pearson did not support Wilders' decision to defy the government.[38]
The deportation was condemned by some members of the British news media.[6] The Dutch Foreign Secretary, Maxime Verhagen, called the decision "highly regrettable” and complained to his British counterpart.[38]
