It seems to me that the value comes from the granting of planning permission in respect of the land. If you are going to argue that that has to be shared by the community as a whole, not just the local community, surely you need mechanisms to get that value raised and to redistribute it. You could not do it on the basis of the current tax system.
This takes me back to a point that I was going to make on the amendment. I recall that when I first went on Luton Council, in the mid-1970s, we had something called the Community Land Act, as I recall it, and the development land tax. It was then very much the name of the game for developers to go and dig a trench to demonstrate that they had started their development before those provisions kicked in. Normally, there was a photograph taken with somebody holding up a copy of the Times, or whatever, to validate that this was when they had actually dug the trench.
