In terms of the organisations involved, the investment is top heavy. 25 companies out 24,000 is not a good ratio and seems too much like having all your eggs in one basket.
Most of the EU is suffering economically and the value of our investments there, in terms of returns, are being dragged down. Even Germany is in doubt with fears that the Deutsche Bank my imminently fall, raising alarm that if we don’t reach an agreement quickly then Britain will potentially have to help bail it out.
After Europe British foreign investments lie with the US who own the largest chunk of British businesses in terms of numbers. The fact that the US is not Europe is a bit a relief and of course that we have always fostered a ‘special relationship’ with them. However, we have to take account of the Trump factor. Should Brexit not be seen by the US as a good deal then he could invoke ‘America first’ and take his business home. There’s no telling with Trump.
