What gives me the confidence is that I think it is perfectly doable, and I think the Secretary of State intends to do it. I am in a slightly odd position-the Secretary of State has to nod each time I say these things, because I cannot speak for him-but I assure the hon. Lady that I really am very confident about that. Let us proceed for a moment, however, on the assumption that that is indeed going to happen. That gives us a place in which to do things, although of course it does not solve all the problems. My second point is that, unlike the hon. Member for Brighton, Pavilion, I think that a national policy statement is an ideal vehicle for the translation of these principles into something much more solid and much more determinate. A national policy statement is not just something that a Minister dreams up and issues like a piece of confetti. It comes before the House of Commons and is subject to resolution by the House of Commons, and it is therefore debated. It is exposed in draft, and it is discussed by the green groups. There will of course be considerable debate about the exact terms of a national policy statement that seeks to turn those principles into something much more concrete, but I think there is ample scope for turning it into something of which we could be really proud. It would also have a huge advantage over mere principles when the courts came to judge the actions of the state and measure them against it-for that is exactly what would happen. A national policy statement is a policy statement by Ministers. If Ministers do not follow that policy, they are, by hypothesis, acting irrationally and in a Wednesbury unreasonable way, and can therefore be judicially reviewed. When they are judicially reviewed, the courts will look at the policy statement and compare it with their actions. If the policy statement is properly debated, properly exposed and properly expressed, those actions can be measured against it in a very determinate and careful way, and we can end up with a much more solid environmental protection than we would ever have got out of the principles.
