Despite the fact that there's billions of dollars sitting in the Iraqi government reserves, somehow they are incapable of getting it out to the people. There are a very large number of people here who are on the edge of starvation. For those sort of people - a sizable chunk of people - that service makes them regard Muqtada as a sort of god.

Young Shia who have been brought up with nothing, who are pretty anarchic, pretty dangerous. In 2004 when they came close to killing me, and of course they have killed very large numbers of other Iraqis. That's a major source of strength for Muqtada.

But from the moment George Bush decided to overthrow Saddam, the people who were going to benefit here were the Shia, who are 60 percent of the population. So if you were ever going to have an election, then the Shia would take over.

There's a lot of expectation in the Middle East that post-Obama there will be a sort of tougher U.S. line on Assad, there will be more intervention and so forth. But I don't know if that's going to be fulfilled. If there is more intervention, then I think it's going to go the same way as these other interventions that we've seen in Iraq, we've seen, to a degree, in Syria, we've seen in Libya, you know, that they do really badly. They make bad situations worse.

Mosul stands rally at a sort of juncture of sectarian and ethnic differences.

Muqtada leads the only real mass movement in Iraq. It's a mass movement of the Shia, who are 60 percent of the population, and of poor Shia - and most Shia are poor. Otherwise the place is full of sort of self-declared leaders, many of whom spend most of their time outside Iraq.

It's always sort of amazing, sitting in Baghdad, to watch visiting dignitaries being received in the Green Zone by politicians who have usually very little support and seldom go outside the Green Zone.
