Carne Ross, the UK's Iraq expert at the United Nations from 1997 to 2002, has a poor opinion of the quality of the questioning at the ongoing Chilcot Inquiry into the Iraq war.
Ross told the BBC that chairman Sir John Chilcot was running a "narrow" investigation, with the standard of questioning "pretty low".
He went on to say that the Chilcot inquiry was not doing enough to ensure it got a full picture of events.
"The other government witnesses are giving a partial view... I think that the standard of interrogation by the panel is pretty low. The level of questioning is very easygoing.
In particular my greatest concern is that witnesses are not being challenged on the contradictions between what they are saying to the panel and what's in the documents."
These allegations are nothing new, from the very outset journalists have been saying that witnesses have been given a very easy time by Chilcot.
