For one of the the Beeb articles, this one was the one that sprang to mind immediately, click here.
And note the date of the article.
Doubts about a claim that Iraq had tried to buy uranium from the African state of Niger were aired 10 months before Mr Bush included the allegation in his key State of the Union address this year, a CIA official has told the BBC....But the CIA official has said that a former US diplomat had already established the claim was false in March 2002 - and that the information had been passed on to government departments, including the White House, well before Mr Bush mentioned it in the speech.
Obviously the "CIA Official" might be someone close to the "diplomat" - ie, their spouse.
