I say to the Taliban: surrender the terrorists; or surrender power. It's your choice.

One of the things that I've been doing over the past few years is reevaluating my own powers of political analysis.

There are people who are anxious about immigration for reasons that are perfectly sensible. They think it's uncontrolled. They think it's, therefore, arbitrary in its consequences, and there are some communities affected much more deeply than others.

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

We need to develop the new green industrial revolution that develops the new technologies that can confront and overcome the challenge of climate change; and that above all can show us not that we can avoid changing our behaviour but we can change it in a way that is environmentally sustainable.

And just as the terrorist seeks to divide humanity in hate, so we have to unify it around an idea. And that idea is liberty.

The first rule in politics is that there are no rules, at least not in the sense of inevitable defeats or inevitable victories. If you have the right policy and the right strategy, you always have a chance of winning. Without them, you can lose no matter how certain the victory seems.
