Comment on this programme
When the Home Secretary was shouted down at meeting in the East End today, heads were turning at the Newsnight office.
The man making all the noise was Abu Izzadeen, who first appeared on Newsnight last year as a member of the radical and now banned Islamic organisation, al-Ghurabaa.
Richard Watson's interview was one of the first to show how extreme some elements within British society had become. Tonight Newsnight asks if the moderate Muslim community is doing enough to stop extremist opinion.
The accusation just won't go away that the giant oil company Exxon (that's Esso to you and me) are funding groups and institutes who are willing to argue, in the face of overwhelming scientific evidence, that global warming is not caused by human activity.
Tonight we're hoping Exxon will face one of their principle accusers, the environmentalist George Mombiot.
We're not quite sure if the oil men are going to turn up at the moment. Watch this space.

Sixteen years ago, Sue Lloyd-Roberts shocked the world with her report on the treatment received by children in Romanian orphanages.
Anyone who saw those images of young children being tied down in their cots is unlikely to ever forget them.
Tonight Sue returns to find out what became of those children and those orphanages, three months before Romania plans to join the European Union.
