Abramovich - Godolphin and Latymer - is another one. Obviously, most names and schools will have been kept secret, because it doesn’t suit anyone (certainly not the establishment or the schools themselves) to publicise where specific children went or go to school, even if it is not a data protection issue. Besides which, to be fair, if the money has already been whitewashed by other parts of the British establishment before it gets passed onto the schools or universities, then why should they question what others who definitely knew better chose not to?
Of course, it all depends on what you count, as it has long been an open secret that (known to be) corrupt oligarchs from former soviet socialist republics particularly liked London, London’s financial services industry, and UK private schools as places to whitewash their money and reputations. Unfortunately, because the money was so enthusiastically accepted by the establishment, this tarnished the UK’s global reputation (except as a good place for money laundering, that is). Increasing numbers of leaks (eg the Panama Papers and Pandora Papers) and investigative journalism (eg reporting behind said papers, and also try reading the book, “Kleptopia: How Dirty Money is Conquering the World”) further harmed the UK’s reputation, as they revealed quite how much the UK, UK businesses and British overseas tax havens had profited from helping hide money and not questioning very deeply where the money came from. Putin clearly believed he had compromised the British establishment so effectively that he could even murder people on British soil and not get much in the way of meaningful comeback.
The invasion of Ukraine has, of course, caused the UK to change its attitude towards certain behaviours by particular individuals it was clearly highly relaxed about when it suited it - not because those individuals have only just been discovered to be corrupt, but because the country can no longer benefit from any association with them.
Whilst the whole world is corrupted by the behaviour of powerful oligarchs, it’s really hard to argue that the UK did not funnel and accept more than its fair share of dirty money in the last few decades, and that this money enriched some more than others (it did not trickle down that much, as it was mostly hidden for tax purposes). So, it’s up to you what you make of that - honest mistakes, because the money seemed legitimate, or eyes so deliberately blind they couldn’t see the harm in accepting it.
