BBC NEWS | Middle East | Iraq war debate fuelled by report

Key findings in the report:

"The ISG has not found evidence that Saddam possessed WMD stocks in 2003, but [there is] the possibility that some weapons existed in Iraq, although not of a militarily significant capability."

"There is an extensive, yet fragmentary and circumstantial body of evidence suggesting that Saddam pursued a strategy to maintain a capability to return to WMD after sanctions were lifted... "

"The problem of discerning WMD in Iraq is highlighted by the pre-war misapprehensions of weapons which were not there. Distant technical analysts mistakenly identified evidence and drew incorrect conclusions."

The ISG also published a list of people and groups to whom Saddam Hussein allegedly offered cheap oil in return for their support in trying to get UN sanctions lifted.

Many on the list - drawn from official Iraqi documents - are from Russia, France and China - countries which opposed the war in Iraq.
