I remain a liberal. As I have explained often with regard to my views on specific political questions, my political thought sits in a tradition handed down from Hazlitt, Bright, John Stuart Mill and Gladstone. That will always be the case. I joined the Liberal Party in 1973.

There is much to be said for consistency and for loyalty. But I really cannot with conscience look at the reforms to introduce private profit into the NHS and the state education sector, and remain a card carrying member of a governing party. These are not small points. So I have left.

I shall not back any political party in England. I have always supported Scottish independence, and I have now taken out a formal SNP membership. There is no perfection in practical politics and should be no idols. But Alex Salmond and his people are doing a decent job in an imperfect world. For reasons I gave recently, breaking up the British state and its resurgent neo-imperialism and neo-conservatism is a political priority.
