“We’ve become like an emerging economy country where when the Prime Minister coughs the currency wobbles.” So said my friend the seasoned politico-financial journalist on Thursday 22 November as we took a bite to eat while waiting for Mrs May to make her statement in the House of Commons on the “Political Declaration setting out the framework for the future relationship between the European Union and the United Kingdom”.

The company that employs my friend has instant, constant and global reach. His remark made me think that the multiple, molten uncertainties in which we have lived since the referendum of June 2016 have left the whole country living in a kind of floating exchange rate not just with Europe and the rest of the world but within the UK too.
