I wasn't thinking of the UK CAA specifically but my comments apply here also.
In my particular area of interest the CAA has a responsibility to regulate financial performance of some aspects of ATC service provision and also the safety performance. Similarly, there is often great resistance to the allocation of airspace when it may be appropriate on grounds of safety.
Despite your occasional assertions to the contrary, however, I believe that the UK has a reasonable set of arrangements and, in the main, a responsible and robust regulator managing them.
As I said before, it's not easy being a regulator - and it's very difficult to understand the regulatory framework that is established in a country (or domain) without spending considerable time working within it. A snapshot view, which is all one is likely to get with a government sponsored review, will almost inevitably fail to gain that full understanding.
