The report is by the competition commission and has indicated that the Government agency has not regulated the various airports around the UK in the manner it should of. It said that the CAA has no backbone.
You only have to look at the CAAs "Mission Statement" to see that:
The CAA’s mission is to provide best practice regulation and expert advice that are independent and enable civil aviation to best meet the needs of its users and society in a safe and sustainable manner.
The CAAs part time chairman, an accountant, was appointed by the Blair government, to downsize the CAA as part of the governments capitulation to EASA. He has done a good job downsizing his "business" by allowing knowledgeable staff to leave (managers get bonuses for saving a salary) whilst replacement requires a "Business Case". Needless to say there is no hand over, no training, and above all the knowledge is lost for ever. No wonder so many staff have left voluntarily!
Best practice regulation in a safe and sustainable manner is hardly REGULATION FOR SAFETY. There is no leadership from the very top.
