It's easy for them ... Simply go and live where everyone else is loaded and then nobody gives a toss ... Monaco (for example) with the loot safely deposited in Grand Cayman would do ... No UK Tax and a great climate to boot ... Everyone's a winner.
Don't stay in the UK though ... Waste of time and money.
Just for a laugh. I would buy a whole housing development off plan....There is one in particular in Sussex then I would name all the roads/closes to reflect the true nature of the place. ie. Thatcher Drive Falklands close. Asylum Lane Yes, it`s a Care in the Community sell-off of a Large Mental Hospital And I would rent the lot and live off the plebs` money Leasehold 99 years max., of course.
