Razor, the value of the pound is a reflection of the confidence of the markets in the UK economy in both the short and long term. The referendum result immediately created a period of selling sterling and it's now trading at a lower level and is showing no immediate signs of returning to its former levels. However, the low productivity of the UK economy is also a factor in the markets. If you're telling me that investment in the UK economy either from home grown resources or inward foreign investment is likely to increase after we leave then I'm going to disagree with you. Given the glee that some seem to have for a hard Brexit, any foreign investor looking to gain access to the European market by manufacturing in the UK is going to look elsewhere.
I'm fed up with things that I've been told by leavers that one by one have proved untrue. To quote a few notorious examples. David Davies saying that the deal to leave the EU would be one of the easiest we have ever undertaken. Only to be followed a few months later by, this is more complex than a lunar landing. Or how about Liam Fox, on day one after the referendum we will be going to Berlin not Brussels to get a deal, suggesting that individual countries would want to do deals over the EU's head. That, of course, has turned out to be bullshit. And of course we still have John Redwood with his, German car manufacturers will force Angela Merkel to do a deal. This week the German equivalent of the CBI set up a task force to plan for the UK leaving with no deal. Does that sound like they're desperate to do a deal ?
