I am grateful to the hon. Gentleman for his contribution. As he indicates, this is—I think by common consent—a rare issue in the first place, not that that diminishes the importance of ensuring that we get it right. It is very complicated, as he has indicated; different leases will have different elements within them and it is impossible to comment on every single case or every single instance, as has been indicated, because of the complexity. I am not aware that there is an indication that there is a general reduction in the value of leases for the very small number that this will cover. I will write to the Committee if what I have just said is incorrect or needs clarification in any way. I hope that, on that basis, we can make progress.
