At the heart of my politics has always been the value of community, the belief that we are not merely individuals struggling in isolation from each other, but members of a community who depend on each other, who benefit from each other's help, who owe obligations to each other. From that everything stems: solidarity, social justice, equality, freedom.

Anywhere, anytime ordinary people are given the chance to choose, the choice is the same: freedom, not tyranny; democracy, not dictatorship; the rule of law, not the rule of the secret police.

I had discovered long ago the first lesson of political courage: to think anew. I had then learned the second: to be prepared to lead and to decide. I was now studying the third: how to take the calculated risk. I was going to alienate some people, like it or not. The moment you decide, you divide.

My view is that we're entering into a situation of enormous instability, insecurity, fragility.

When my parents were growing up the world's population was under three billion. During my children's lifetime, it is likely to exceed nine billion. You don't need to be an expert to realise that sustainable development is going to become the greatest challenge we face this century

In Downing Street they called me 'Boss'. Civil servants would always call me 'Prime Minister'.

Our determination to defend our values and way of life is greater than their (terrorists) determination to cause death and destruction to innocent people in a desire to impose extremism upon the world.
