Perhaps it's to catch out those who were not born in the UK and have weasled their way into the UK illegally?
Or is it to stop the huge ammount of Criminal Freud here in the UK?
Along with all those biometric thingies thay want to add as well, who do THEY believe WE are?
So far it has changed from YOU MUST, to now ALL Students and those in high risk (Airports) will have, does that include all the illegal's they have working in the security industry?
Well done the Home Office and the dept dealing with Passports, lets not forget, they could always get allot of the cost back, by selling details onto private companies, much like DVLA did some years ago!
