rogue leader
Short answer. Because the UK has withdrawn from EASA the oversight and enforcement of which is the ECJ which the UK has demonstrated it does not want to be ruled by. This was all fully explained ad nauseum before during and after the UK vote. No body wanted to listen, because, well, bananas, £350M to the NHS etc. we wanted sovereign rule and autonomy. We have it. The consequences are clear and obvious. I feel for sorry for all avaiation licence holders. we were lied to by government, again. (I still have my letter from my MP assuring me that the UK would be staying in EASA).
