'Second Home' Secretary Jacqui Smith decided that Geert Wilders is an ‘undesirable’, and ordered the UK Border Patrols to intercept Wilders’ arrival and arrange for his immediate return to Holland.
She had no qualms about allowing an ex Russian army officer, Vitas Plyntnkas, convicted of a vicious killing in Germany in 2001, into the country. Germany had formally deported Plyntnkas to his homeland of Lithuania in 2005, but that didn't ring any alarm bells.
In the UK, he carried out some minor thefts that came to the attention of the local police, but it was not before he had cut off the head of a fellow Lithuanian and stuffed it into a Lidl carrier bag (amongst other minor details) that anyone questioned his right to roam free within the EU. He is now facing life in a Scottish prison - and presumably someone somewhere will - eventually - be considering whether they might possibly think about asking him whether he might mind if they deported him.
The 'public interest' question that was so speedily applied in Geert Wilder's case didn't get a mention.
