The CAA's priority is the continued prosperity of UK airlines. They have no interest in acting to ensure safe operations. So unless the Daily Mail presents them with a smoking gun (or a smoking hole) it's business as usual at the CAA.
Around 10 years ago the UK had a mature sensible FTL scheme. The regulations were formed over many years as a result of accidents, incidents and deaths where we promised the bereaved that we would learn from our past mistakes. Then one day we threw that ruleset in the bin in favour of a Pan-European system that bore no resemblance to either of the 'Gold Standards' of the UK or Germany.... All in the name of EU political expediency.
