Given the Queen has a nice cozy arrangement with herRC where she (well, her fiancial bods) get to choose what (relatively miniscule else it would be publicized) amount of tax she pays then Cayman stuff would be financial bods on autopilot as their usual legal (cos laws are useless), but morally reprehensible offshore stuff was not needed.
Not enough hassle of queenie for investing in BrightHouse, a company thet exists to shaft poor people with loan shark levels of interest repayment (where a bog standard fridge can easily be over a grand in repayments over several years): SHe has people doing the finances for her, but it;s not difficult to say only make ethical investments, do all finacial stuff in a transparent and above board way.
Still, living up her figurehead of teh nation status, rich elite screwing over the proles is what the UK is all about.
