This is what Robin Cook had to say during his resignation speech
"Iraq probably has no weapons of mass destruction in the commonly understood sense of the term - namely a credible device capable of being delivered against a strategic city target.
It probably still has biological toxins and battlefield chemical munitions, but it has had them since the 1980s when US companies sold Saddam anthrax agents and the then British Government approved chemical and munitions factories."
And the best bit
"Why is it now so urgent that we should take military action to disarm a military capacity that has been there for 20 years, and which we helped to create?"
As Robin Cook read every single MI6 intel document on Iraq as part of his job as foreign secretary from 1997 - 2001 he knows what he's talking about.
