More on dossier-gate;

Donald Anderson, chair of the foreign affairs select committee, demanded that he be allowed to question the chair of the Joint Intelligence Committee (JIC), who oversaw the production of the government's reports.

Mr Straw refused, saying that it would be more appropriate for the JIC chairman to appear before the Commons intelligence and security committee, the proceedings of which are confidential.

Mr Anderson told Mr Straw: "In effect you are using this jurisdictional point to stop the committee having what could be absolutely decisive evidence."
