Er would that be like they have with every other country in the world ?, I dont see any free movement going to the USA or Japan, or hear that the yanks are paying some kind of membership fee to flog pepsi.
ANY exporter will have to meet the quality/ safety standards of the country it exports to, ours are equal or superior as a matter of course.
The EU will still be welcome to buy and sell with us, only a fool thinks they want a trade war of imposed tariffs because we would win it hands down.
Someone should tell the Norwegians. They keep paying in when they don't need to!
Interesting article in The Times today from Oxford Economics. They've modeled 9 different scenarios and concluded that it is possible for Brexit to have no adverse financial consequences. But only if we retain strong links with the EU, including retaining free movement of labour, whilst also negotiating free trade agreements with the non EU countries. They also reckon the tariff war scenario would lead to a reduction in UK GDP of 4% by 2030. The GDP reduction for the EU in this scenario would be 0.2%. Not exactly winning hands down.
