The only issue with the 'not spot' route, is how do you define a 'not spot'? Or perhaps more importantly, who will be defining it?
Will it be the operator? In which case, are they only going to go as far as providing a token effort then giving up when the £150million is exhausted?
Or are Ofcom going to try and do it? Are they even allowed to tell a private company where they must place resources?
