Thank you, Mr. Deputy Speaker, for rescuing me from having to reply.
The second test is this: does the technology exist to make the system work? Again, the Home Secretary has not answered the question, but other people have. One group, which knows far more about these things than our famously technophobic Prime Minister, said:
"This will undoubtedly be a large and centralised system as currently outlined in the bill, and this type of system attracts a high risk of failure."
That was the British Computer Society, which I suspect knows rather better than others what it is talking about.
One of the most potent criticisms of the Government's plan, however, is that it will make fraud easier. This card will become a master key for fraudsters. Its intention is to give, if I can use the Home Secretary's words, "legitimacy" to someone's identity, but if that identity is fraudulent in the first place, it only makes the problem worse. One expert in this area says:
"ID cards will exacerbate the situation. The stakes are raised that much higher if the master key is cracked; it opens the door to all sorts of frauds."
It is extremely likely that this ID card system will actually make fraud easier by doing exactly that.
