Claim
The UK is the EU's single largest export market.
Conclusion
That's right for the goods market. If you treated the UK as if it were out of the EU it would have made up 16% of the EU's goods exports in 2014. That's just ahead of the United States.

No more than a distraction, e'hhh. Some distraction. Quit driving yourself to distraction SA- leave it to the adults. There is nothing you can do now except moan, and throw in the odd piece of nonsense as above.
