A week pound improves exports but makes imports more expensive. Amongst other things, imports such as oil. Ignoring tariffs (which may come later) price increases directly cause inflation. Toblerone have already taken drastic action

, VW have announced price increases, and Unilever are strongly hinting at them so this isn't something that might happen, its already happening. Inflation, unless earnings rise hand in hand with it, decreases demand for goods. Inflation also usually leads to interest rate rises and, at present, aren't we at largest ever personal borrowing levels at £1.5 trillion? The IFS have predicted
a £25 billion additional borrowing requirement for the government in this parliament directly down to Brexit - that's £25 billion taking into account EU contribution savings! If that proves to be the case how is Brexit economically a good thing?
I'm not talking about concerns over immigration. Lots of people, brexiters and remainers, Germans, French, Dutch et al have concerns over that. I'm talking about out and out racism.
