Mostly spin and bull**** I am afraid, the CAA is largely an empty vessel, the DfT have delegated everything except LAA and Annex 2 to the EU and EASA. The CAA is bound to follow EU regulations and will do so slavishly as is the UK habit whilst others pay only lip service.
Obviously EASA makes it harder to action change because it means another party to satisfy. There is more flexibility in the relationship than is commonly believed though and despite initially being very slow off the mark to deal with EASA there is now more of an opportunity to change things than there was previously.
