Minor diversion.
I was struck by the mention in one of the "Follow the data" pieces of a chap called Roger Gabb. He's a British pro-Brexit Tory donor, shareholder in Cambridge Analytica (or SCL Elections, I couldn't make out the prose), and... owner of South African wine company Kumala who has owned a vineyard nr Stellenbosch since 1995.
Aaron Banks, millionaire backer of UKIP and co-founder of Leave.uk, is also a British businessman with strong links to South Africa - grew up there, owns a diamond mine there.
This might be nothing, but the "Follow the data" articles highlight the significance of personal introductions and networks. They show that organisations which on (most bits of) paper are completely independent, are in fact deeply interrelated.
So the popping up of two South African-connected chaps has tickled my senses. Ultra-rich, white South African circles constitute a fairly small pool. People know each other. They're often internationally dispersed, particularly after the violence and uncertainty of the 1980s/90s, but effortlessly span the continents.
And just to throw something further into the mix, white supremacist beliefs aren't exactly unknown in this group. They either grew up with the racism and "swart gevaar" and narratives of "the superior white race under threat from the black tide", or were attracted to South Africa by same (sadly true).
I'm not suggesting all white South Africans are white supremacists. But it was a country where white supremacism was encoded in law and society for many decades, and that doesn't go away the moment you elect a new government.
Like I say, might be nothing. But it may be worth just keeping an eye open for more South African links.
As you were.
