sorry Robin-get bit prickly at suggestion that ATCO's sole purpose in life is to keep GA out of controlled airspace!
having seen what is now involved in getting any airspace application approved, and the hoops that must be jumped through when you have it then any further major expansion unlikely
on a personal note can not see why mandatory carriage of XPDR is needed, but then so far down food chain not likely to listen to me! seems to be the favourite flavour of the month, why you need to make a known traffic environment out of class G is beyond me
Pudnucker-you may be interested to now that we are required to log all transits, deviations and refusals of our class D, data passed to CAA
