"I suspect that we'll be seeing the relaxing of regulations requested by the US corporations in TTIP the second we have left the EU as a way to try to rescue our fucked economy."
Yes, I also think that will be one of the first results. We have a "special relationship" with the USA and the UK now needs to hurriedly start setting up new trade agreements. Article 50 has to be invoked sometime over the next few months then there's a maximum of two years to negotiate the exit from the EU. That's no time at all in terms of negotiating trade treaties. The US will know this so we'll almost certainly end up with a TTIP agreement with no time or real economic power to curb the worst of it. And after 40 years in the EU I doubt the Commonwealth countries will clamouring to offer us any favoured trade deals.
