Other than the fact we might not be able to trade under WTO terms after we leave the EU, Gove claiming he tried to call Boris and Team Boris calling it rubbish and both of the favourites for the leadership saying nothing will be triggered until 2017 at the earliest and Osbourne saying the target for reducing the nations debt isn't going to be hit by 2020 due to leaving (which is probably a convenient get out clause), sure.
I think that's a case of jumping at everything now, no matter dangerous or not.
*Obviously* in order to be able to trade with EU (or anyone else) on WTO terms, we have to become a member of WTO first. *Obviously*, if everybody drag their feet on this and other things, the country will first spend years getting out of EU, then a year or more getting into WTO, then some more time striking a deal with EU. *Obviously*, the EU guys are making strong faces and telling everyone that, yes, that's how it's going to be, and that no, they don't see any other way.
But that's just a negotiation position. Everything here is subject to negotiation. Preliminary work on entering WTO can and should be done. The UK can work on deals with other countries, aiming to close them quickly after quitting the EU. The UK *can* negotiate with the EU about the future deal and about anything else. The UK doesn't even have to enter WTO to trade with the EU on same or similar terms, the new deal can include these terms without ever using the name "WTO".
Yes, the UK perhaps depend more on the EU in general than the other way around. But it's an inter-dependency. The EU *also* depend on the UK.
So, I think it's time to stop jumping at every tweet, take a step back, decide the course and move on. I don't see the sky falling. If someone thinks it is, fine, I understand, but I'd re-check some time after to make sure it really is falling.
