I know I'm repeating myself, but anyone talking about deals to be made with other countries literally doesn't understand how these things are done or what's required.
Firstly, we literally can't do them. Legally etc, until we invoke article 50 and the two years has passed, no trade deal.
Secondly, we actually can't do them - we haven't had trade deal specialists in the UK for 40 years. Any we had went to the EU a long time ago. These things take years and legions of civil servants for a reason - and we have precisely 0 right now. At exactly the same time as we begin the largest and most complicated legal and diplomatic challenge in human history (no joke) - removing the UK from the EU.
Thirdly, of course, there's the market issue. The EU is 45% of our export market right now. You aren't going to replace the worlds largest single market, that is literally off-shore. with a hodgepodge of smaller countries on the other side of the globe.
There will be trade deals, in the end. But it will be a decade until we see them, and meanwhile we will have to undergo crippling burdens as we won't have the single market anymore. It would be economic destruction on an unparalleled scale on small and medium business for them to lose the EU and not have a replacement. And there is no replacement - the best we will do is a number of bilateral deals that are smaller in scale and scope than the single market, decades from now.
Trade is not easy or simple. There's a reason they take years and years to complete. The laughable notion put forward by leave politicians that 'other countries are queing up' is a simple lie.
