The Germans, in particular, are apparently extremely jealous of London's pre-eminence in the global markets for sharedealing and insurance.
Somewhere in a smoky room they and the French will be cooking up a scheme to "make it fairer" for all EU countries to have access to these financial sectors. You can bet your life they'll try to introduce quotas.
TBH I reckon we'd all be very sorry afterwards. There are a lot of benefits from being in the EU. But the biggest is that we have a say in what they decide. Once on the outside we'll lose that say but we'll still have to abide by their regulations if we want to trade with them. Plus of course in trade with the rest of the world we benefit from any benefits the EU can negotiate for us. We are a small insignifcant island off the North West coast of Europe globally we'd have no influence at all once outside the EU. All this talk of conspiracy by the Germans and French to "do us down" is the basis of the arguments. Bascially those who want us out want to be free to make as much money as possible out of moneyfor themselves. But the rest of us will be up ###### creek without a paddle. But they don't care about that - they never have and they never will.
