An interesting point from Jon Moynihan who is on the board of Vote Leave and has been speaking at the British Chambers of Commerce conference today.
He says we need to stop referring to the EU as the world's biggest tariff-free trading area, because it is only that if you include the UK.
If the UK were to leave the EU, he says, then the economy of the US would be bigger than the EU.
There is agreement on the figures behind this point, with the graphic above appearing in yesterday's paper from the government on the alternatives to EU membership.
