As Nigel Lawson acknowledged in his book ‘An Appeal to Reason’, – I too really admit that I am not a scientist or an economist. But then neither are the vast majority of those who pronounce on such matters as covered in these articles with far greater certainty than I do herein. Nor are those who have to take key decisions about these critical issues. Rather they are responsible politicians, who having listened to the opinion of the experts, must reach the best decision they can in the light of all the various expert opinions available to them. So must we all, and I have herein tried to present the matters as I, an informed layman, sees them to help you, the reader, to do so too.
