My office is on Twitter. I don't tweet myself - at least, not intentionally, but I probably should do.

The problem is some of the populism on both the far left and the far right, it can make a Tweet but not make a policy. And, you know, when you are dealing with issues that are as important and serious as this, I understand why people search for simple solutions.

You know, the media and politicians are always gonna be in a bit of tension with one another and probably most of the time that's healthy and indeed even creative. But it's where - it's really when news organisations are used as kind of instruments of politics that it gets tricky.

Where radical Islamism is going to be a factor, it's going to be very, very tough.

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.

We have taken a situation in the U.K. because of concerns, for example, over immigration and other things, so Britain now is on a path out of Europe.

Actually the royal family were very gracious and good to me. But I also found that the British establishment were never quite sure what to make of me. I was a Labour figure, but I'd come from a very middle-class background. In one sense I offended both traditional right and traditional left. But I thought that was no bad thing.
