I disagree Turambar. I'd like to see UK exit immediately on WTO terms foreshortening period of uncertainty for both EU & UK. The costs of tariffs for UK exports are already negated by currency depreciation whereas EU exports to UK with tariffs are less attractive & uncompetitve on price. A fall in imports would be good news as UK has a very large trade deficit. Only real issue is financial passporting which will mean some jobs moving to the continent but against that is less interference by Brussels in financial services ~ we can kiss goodbye to threats of a FTT, or a common corporation tax. There is no single market for services so whether we're in or out isn't an economy killer. Like it or not London is the deepest market for capital and EU companies will use same regardless of whether UK is in or out as none of the other EU centres have anything like the competencies.
