From the London Times last week:

“After the July 7 bombings, Tony Blair insisted that the “rules of the game” had changed and two weeks ago Mr Clarke announced new rules for deportations with a pledge that moves would take effect “very quickly. The next few days.” Since then no action has been taken against any extremist under those rules. Immigration officials and police were given a list of targets to arrest, but the first raids were called off at the last minute with no explanation…”

And this…

“One Spanish source close to the investigation into the Madrid bombings said yesterday: “Britain is still the weak link when it comes to extremists. A dozen countries have asked for the extradition of suspects living in Britain, and not one has been handed over since the September 11 attacks.”
