I wish everyone would stop the panic about Brexit. It is in Europe's interest as well as ours to do a good deal. Take the motor car industry for example. Mercedes Benz, BMW and VW have a vested interest in there being a good deal. VW in particular has more to loose than most. Not only are jobs in Germany under threat but also those at Seat in Spain and Skoda in the Czech Republic. As I understand it Volvo's biggest single market is the UK. That's Sweden as well.
Apply the Dad's Army Principle. There are so many Private Frasers around saying "Wur doomed, doomed". But look, here's Corpral Jones; "Don't panic, don't panic. When you stuck you've got to show them the cold steel".
In threatening a hard Brexit Theresa May might be seen as showing them the cold steel. When it comes down to it you know what Corpral Jones said about showing the cold steel.
Indeed the pound dropping has actually benefited the UK economy. Our goods are now more competitive.
Stop pinicing, that's what causes the problems.
