The former prime minister has been in the pay of the Kuwaiti government and a South Korean oil firm for up to 18 months, a parliamentary watchdog has revealed.
In a further revelation, a classified memo from Mr Blair to President Bush showed the full extent of his support for the toppling of Saddam Hussein.
The personal note — which has been seen by the Chilcot Inquiry but not released by the Government — shows that Mr Blair wrote: “You know, George, whatever you decide to do, I'm with you.”
