So is it the MODs to sell
I seem to recall this cropping up before and hearing that the Rothchilds (or similar) granted use of the land but retained first 'dibs' on it if the MOD no longer wanted it.
Plus there was also something about 'having to return it to its original state'.
IIRC this was not the only unit under that umbrella.
Could be wrong of course as it is a long time since I leapt over the fence
