Please update us Alan. I found much of the book I read to be fairly skin crawling: not just because of the Nazi/fascist connection but because of the whole privileged attitude to the rest of society.
A partial list of the most prominent Right Club members. The extent to which the British aristocracy, and Royalty, beyond just the Windsors, were committed to Hitler might seem quite remarkable.
Red Book: Membership list of Captain Ramsay's Right Club - Archives Hub
An interesting list of influential Hitler fans is presented. It goes well beyond those willing to be identified as members of a Fascist club.
I have been unable to find or buy a full list of Right Club Members and sympathisers anywhere. Though the partial list along with all the connected people who though not members were fully sympathetic is considerable and ought to be surprising.
A good read but rather too focused on Unity Mitford for my taste, though still revealing of a good deal I didn't know about her and her family. They were a rum lot. The Windsors naturally feature to a good extent and look worse in the light of what's said here than I previously knew.
All of this information, including information on events at the time and the complete and very deliberate and fully considered lack of official action at the time, including many last minute high level political interdictions to prevent law enforcement and the security services stepping in to detain and question many influential people made interesting, but not at all surprising reading.
It is scandalous, but not surprising. Given the lack of information I'd say that every effort is still being made to hide it. Many files thought to be pertinent are still classified and have regularly had their period of classification extended. That's The Establishment at work, even long after all concerned are dead their has to be a pretence that they didn't behave reprehensibly.
The knowledge these people have that the rules, the law or decency towards the inconsequential members of society's lower ranks don't apply to them is implacable. They are fully entitled to do as they please and if others can't see that then the fault lies with those others.
