I am presuming it is the Irish regulator that looks after Ryanair? Are they vigorous or a bit tame, as the tax authorities seem(ed) to be in Ireland for companies such as Apple, or the data protection watchdog (in the past at least) for Meta/Facebook.
When I worked for a couple of Irish airlines some years ago they were the ultimate rubber-toothed poodle running a cosy little favours club for their ex-Air Corps mates who ran the airlines.
