We had to fight the enemy without in the Falklands. We always have to be aware of the enemy within, which is much more difficult to fight and more dangerous to liberty.

During my lifetime most of the problems the world has faced have come, in one fashion or another, from mainland Europe and the solution from outside it.

To me consensus seems to be - the process of abandoning all beliefs, principles, values and policies in search of something in which no-one believes, but to which no-one objects.

From my experience let me say this: in today's world it is no bad thing for a politician to have had the benefit of a scientific background. And not only politicians. Those who work in industry, in commerce, in investment. Indeed, so important has it become that I believe we are right to make science a compulsory subject for all schoolchildren.

I was brought up by a Victorian Grandmother. We were taught to work jolly hard. We were taught to prove yourself; we were taught self reliance; we were taught to live within our income. You were taught that cleanliness is next to Godliness. You were taught self respect. You were taught always to give a hand to your neighbour. You were taught tremendous pride in your country. All of these things are Victorian values. They are also perennial values. You don't hear so much about these things these days, but they were good values and they led to tremendous improvements in the standard of living.

It is always important in matters of high politics to know what you do not know. Those who think they know, but are mistaken, and act upon their mistakes, are the most dangerous people to have in charge.

I wasn't lucky. I deserved it.
