Hmmm interesting, so along with Mcdonalds the HQ of BMW would look quite nice in London, as would the HQ of Moet & Chandon. However you salty Euros want to dress it up a company moving its international HQ from Europe to the UK is a win for the UK and a loss for Europe.
There's a reason that since the financial crisis the US economy has grown by 15% the UK by 8% and the EU by 0%.
Honestly the EU is the sick man of the globe who would want to do business there? Nobody it seems.
