No we could simply say we’re out, that’s it.

Thanks for your comment Rosemary. There is a simplistic argument to say that a vote to leave is a vote for sovereignty, while a vote to stay is a vote for economic prosperity. As my article suggests, there is considerable ambiguity, and given the vested interests there is a chance that if we vote to leave we fall out of the EEA as well as the EU, limiting our access to the single market. Whether this transpires or not is, of course, uncertain.
