I mean, I went to a church school when I was younger and imbibed a certain amount of religion then but it was really in university that I got interested in religion and politics at the same time. I don't think as if it were one moment of conversion but my spiritual journey really began then.

The art of leadership is saying no, not saying yes. It is very easy to say yes.

Politics may be the art of the possible; but, at least in life, give the impossible a go.

I mean, you can agree or disagree with Iraq or Afghanistan, but by the way, now the great campaigning cause out there is the absence of intervention in Syria. And then in Libya, it's partial intervention. And that doesn't really explain why some countries that have literally nothing to do with the interventions in the Middle East end up getting targeted.

Global warming is too serious for the world any longer to ignore its danger or split into opposing factions on it.

But as I always say to people I'm essentially a public service person.

Climate change is probably the greatest long-term challenge facing the human race.
