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 would just like to remember some words of St. Francis of Assisi which I think are really just particularly apt at the moment. 'Where there is discord, may we bring harmony. Where there is error, may we bring truth. Where there is doubt, may we bring faith. And where there is despair, may we bring hope.

The larger the slice taken by government, the smaller the cake available for everyone.

I'm standing up for the right of self-determination. I'm standing up for our territory. I'm standing up for our people. I'm standing up for international law. I'm standing up for all those territories - those small territories and peoples the world over - who, if someone doesn't stand up and say to an invader 'enough, stop', would be at risk.

If my critics saw me walking over the Thames they would say it was because I couldn't swim.

The acid test of politics is not what you say at the hustings, but what you actually do in government.

Misgovernment...will often be reflected in oppressive or aggressive policies towards groups within the state or towards the state's neighbours.
