Naaa. As the lovely Mandy would have said "she would say that wouldn't she".
Why ask Frau Regina Karoline Schuller, when her reply was never going to be a surprise. Her script was probably written by Frau Merkel. She who has adopted a King Canute style role in insisting that the Euro will survive in it's current form, although there may be a little self interest along the way.
Also the wording of the missive from Frau Schuller is also erroneous. It was not suggested that Euro notes from certain countries would become "invalid" just that the situation may be reached when their values might differ. What she has said is of modest value.
I have no political allegiance, but as a Brit on matters of Europe I have an increasing respect for UKIP. Of course they have an opposing agenda, but their revelations on the EU gravy train and absence of transparency and democracy is of serious value and Nigel Farage does have a good sense of humour and provides a crystal clear delivery.
