There may have been a campaign to smear the reputation of former MI6 spy Gareth Williams, according to a leading security expert.
Wales This Week has brought together a panel of experts to discuss Mr Williams's death, which is to be the subject of an inquest due to start next week.
Mr Williams was found at his Pimlico flat in 2010. His body was locked in a holdall which was padlocked from the outside.
Since his death there have been lurid newspaper reports about his private life.
However, experts say the reports may be part of a campaign of disinformation designed to besmirch his reputation or take the public focus away from his work.
Sitting on the panel are Gordon Thomas, the author of 'Inside British Intelligence' and Miles Goslett, an investigative journalist.
Wales This Week: Death of a Spy, tonight at 7.30 on ITV1 Wales.
