"The 'tracking' capabilities of the UK ID card system, hotly disputed by Home Office ministers whenever the notion is floated, have been commended by no less a person than former Home Secretary David Blunkett. Speaking on the Today programme on the subject of amnesties for illegal immigrants, Blunkett said "it's impossible to have an amnesty without ID cards and a clean database, because you firstly don't have any incentives for people to actually come up front and register, and make themselves available, and secondly you have no means of tracking them."
