The political climate in the EU is changing, despite EASA clinging onto its gravy trains, but the UK doesn't have the balls to take advantage of it. They could do so, in today's climate, but they won't.
I'm not sure they could. I don't think the UK has as much clout as it used to. The EU is dominated by the Euro area, and the UK seen increasingly as a fringe member, not just in financial matters. When I was first involved in Commission activities (twenty plus years ago) the UK was a required presence in decision making, along with France and Germany (however much the UK sometimes annoyed other countries with a more Atlanticist style). Not now.
Or maybe the CAA has plans but are keeping their powder dry, which is what I would do
What for?
