The Remain camp has somewhat jumped the gun (and revealed their true nature in saying that they want the economy to suffer).
Yesterday it would cost me 50p to buy an Australian dollar. It now costs 54p. Not exactly freefall. The FTSE is down 4%; a significant drop but again not freefall (and much less than the German market which has dropped double that).
The German peak industry body have made clear they will order the CDU to ensure trade continues on a broadly similar basis as they will not accept the EU damaging their business to send a message to others and punish Britain.
Britain's economic fundamentals are sound, and we will negotiate a trade deal with Europe because it's in both our interests to do so. And we can also look forward to something else; the Remain campaign director told parliament that we should not Leave as that would cause wages to rise. As a socialist I say excellent
But we haven't even met!
