My closest friend, who died not long ago, is buried near Marx's grave in Highgate cemetery, so I see the gaggle of admirers laying roses at the foot of his tombstone regularly. I have never been tempted to leave flowers there myself. Great theories, shame about the practice. Marx did many things. But inventing class was not one of them.

So here is one of my theories on happiness: we cannot know if we have lived a truly happy life until the very end. This view of life and death was reinforced by my close witnessing of the buildup to the death of Philip Gould. Philip was without doubt my closest friend in politics. When he died, I felt like I had lost a limb.

I do believe in 'forever' in terms of relationships. There's something really amazing about being with someone for a long time and really knowing each other in that way. They end up becoming your closest friend.

When truth is discovered by someone else, it loses something of its attractiveness.

Man has set for himself the goal of conquering the world but in the processes loses his soul.

I've not been anywhere in Central or South America before. The closest I've been is Cancun and Cabo in Mexico. But I think I'd love the culture, the sprit, and the energy of Brazil.

My brain is a big cluster of stuff. It moves quickly and loses focus quickly, so I need many projects to keep me stimulated - it's a luxury to be able to do lots of different things: style, write, present, DJ or just consult. It can't be any other way; I think I would shrivel up and fall asleep forever.

We have always argued that attempts to isolate Belarus, like other countries, lead to a dead end. In this situation, everyone loses.
