The hon. Gentleman seemed quizzical about, not to say astonished by, the idea that the Opposition parties might commit themselves to scrapping the scheme, even though the Government would have spent a substantial sum of money on it. Given rising costs, flawed technology and our perception of the erosion of civil liberties, why is he surprised by the idea that we might commit to abolish it? The reduction ad absurdum of his argument is that no successor Administration should contemplate changing anything because their predecessors have spent a lot of money wastefully and ineffectively. To me, that is where his argument breaks down.
