I really cannot give that assurance because, in the end, someone has to meet that cost. The problem is that, if the cost fell on the local authority, then there is little incentive for those who are unscrupulous to secure their land, or to take steps to minimise waste. So it is a very difficult issue to deal with, even though I agree with the hon. Gentleman that the vast majority of people are innocent victims. We must ensure that we take steps to stop this practice. I welcome the fact that, in many cases, local authorities work with landowners in dealing with waste.
