And another dossier
Sir Richard was also involved in another controversial moment for the MI6, the publication of the Iraq Dossier in 2003, where the government set out its case against the then leader of Iraq, dictator Saddam Hussein.
The “dodgy dossier”, as it became later known, highlighted the supposed capability of Iraq to produce weapons of mass destruction, making Hussein a threat to the world.
The dossier played an important part in the British involvement in the 2003 invasion of Iraq.
