Re: Autocratic governments, that's a broad brush nowadays.
And? We're the biggest offshore tax haven and funny money laundrette off the coast of the EU. Channel Islands? Paleese! Gibraltar. Come on now. Cyprus? *gives you a pitying look*
The City of Westminster and the City of London is where it's at. All those pretty modern highrises? *Not* owned by Brits, and likely not even *lived in* by Brits. No... they're all owned by random limited companies with controlling interests elsewhere, with again controlling interests elsewhere until at the end of the rabbit hole an Eurasian or African person with connections to <insert despotic tin pot "republic"> pops up.
You might want to read about how much dirty money washes through the great laundrette that is the London property market in a year...
