My own advice to people who would be in office for two or three terms is that they must accept democratic rotation. Ideally not put themselves up for re-election and allow the system to work.

Without a dream you'll not get anywhere.

We cannot wait for governments to do it all. Globalization operates on Internet time. Governments tend to be slow moving by nature, because they have to build political support for every step.

We will not enjoy security without development, we will not enjoy development without security, and we will not enjoy either without respect for human rights.

As we move forward, you cannot resolve the potential food crisis or shortages without science being part of the solution. Science has to be part of the solution but African governments - and these are decisions for governments, whether they embrace or do not embrace genetically modified food - and for the moment, most African companies do not accept genetically modified seeds.

The past year's natural disasters have highlighted the invaluable contributions of volunteers in our communities. They have volunteered their time, energy and skills to save lives and to rebuild communities. In this they joined countless people around the world who volunteer every day in response to 'silent crises'. These often unsung heroes understand all too well that poverty, disease and famine are just as deadly and destructive as earthquakes, hurricanes and tsunamis.

Tony Blair is a very able politician; he's perhaps one of the best of his generation. He made a major contribution in many areas, but in Iraq I believe he got it wrong. He got it wrong.
