Ken Clarke has long been a Euro enthusiast, so his comments are, shall we say, hardly surprising and therefore unlikely to be 'provoking fury' amongst Conservative backbenchers as this report is seeking to suggest. As a well-known Eurosceptic myself, I have to say that Ken's comments are likely to have been rather more nuanced than this report suggests.
It is certainly true that due to the growing turbulence in the Eurozone currency area that there is increasing scepticism in the British public. However, given that Britain has been economically linked to the Eurozone for nearly 40 years, the suggestion that Britain could break that link overnight by leaving the EU is frankly fatuous. What is required is that all of the economic levers in a currency union need to concentrated in a single entity, be it the European Central Bank or something else. That 17 Finance Ministers can make 17 different sets of decisions within a single currency is ludicrous as we Eurosceptics have been saying for many years.
