There is no better example than Branson who is never off the EU phile BBC telling us what a disaster it would be for us to vote to leave the EU. He of course is speaking for his own selfish reasons. As the cartoon below shows he keeps his money safe from the EU's grabbing paws in Switzerland. He also of course has his own island, Necker , in the West Indies his very own Treasure Island where like Captain Flint he can bury his excess gold.
And Branson's not the only one. Ask Sorrell and the other big business BBC EU philes where they keep their own dosh, not in an EU jurisdiction I'll bet. Switzerland, Caymam Islands etc are favoured by big business EU philes.
