You really are thick, but coming from the loony left of the political spectrum I shouldn't really expect anything else. Do keep me updated as and when the investment banks leave London.London is the financial crime capital of the world and leaving the EU won't change that, in fact if anything with more lax laws in the future it will attract more institutions to set up shop.
Go and have a cry and sign the losers petition like all the others on the loony left who hate democracy when they don't get the result they want.
