I would speculate that the reason for more accidents is likely to stem from a the extra regulatory burden and the extra expense that follows that have reduced the hours that people are flying.
One should remember that the UK CAA supervised a system that resulted in a world class safety system that resulted in one of the worlds lowest accident rates.
We now have a system were EU states that had appalling accident rates have influence over regulation, couple that with the European love of over regulation and you have a safety system that has a prime objective of keeping the administrators of that system employed....... Not of keeping GA safe.
