I with you on this howard.
Locking our currency into the Euro would be a complete economic disaster. There was a simple explanation of this published by the Adam Smith Institute recently.
Rather than try to explain in my own words this is a small extract from the paper that explains it simply.
"You can only have one interest rate in a currency area, so if we joined the Euro, we would have handed the control of interest rates over to the European Central Bank. Their interest rates have been lower than ours: indeed, one of the 1990s arguments for joining used to be that we'd have lower interest rates so mortgages would be cheaper. In other words, if we had joined the Euro years ago, we'd have had an even bigger (but equally fake) boom than we in fact had, house prices would be even more astronomical, and the inevitable bust would have been even more painful than it's now going to be.
We're lucky not to be in the Euro, because at least we can let our exchange rate take the strain of the adjustment we now need to make.""""
