There are two outstanding issues in democratic politics these days. One is the relationship with the media, which is now 24/7, and operates with a completely different intensity than even 15 or 20 years ago. How do we have a proper conversation between leaders and country when it's moderated sometimes in a very partisan and inflammatory way? And the second thing is the effectiveness of our democracy. How do we get the right gene and talent pool in politics?

I cannot think of any circumstances in which a government can go to war without the support of parliament.

I say the elite looks out of touch because it's kind of saying; look we'll manage all this for you. You know, we know best. We'll sort it all out for you. And then because people believe that doesn't meet their case for change and they want real change, social media and the way the relationship between people can come into a sense of belonging very quickly, that then is itself a revolutionary phenomenon. You see this around the world.

I'm afraid that's in the nature of modern politics - it's as much conducted by abuse as argument.

There is no meeting of minds, no point of understanding with such terror. Just a choice: Defeat it or be defeated by it. And defeat it we must.

You choose your own reality and you - social media then amplifies those conspiracy theories. So that's why I say social media is itself a revolutionary phenomenon.

This mass terrorism is the new evil in our world today. It is perpetrated by fanatics who are utterly indifferent to the sanctity of human life, and we the democracies of this world are going to have to come together and fight it together.
