In the ‘Brexit’ debate, there are two ideas that simply will not die, however much evidence is thrown at them.
The first is that Britain could leave the EU and then opt back in to those areas of the single market that it liked. The CER’s commission on the economic consequences of leaving the EU, which reported in the summer, explained why this would not happen. The remaining EU countries would not let Britain cherry-pick: the four freedoms of goods, services, capital and labour come as a package. And, in order to maintain undiminished access to EU markets – perhaps by joining the European Economic Area – Britain would have to sign up to all the EU’s rules and standards, but would have little influence over them. For a country so unhappy with ‘rule from Brussels’, it would be an odd choice to cede more power over the regulation of its economy.
