Former British Prime Minister Tony Blair will not be accused of breaking any laws in the Iraq Inquiry report, the Sunday Telegraph can disclose.
Sources close to the inquiry said the report, which will be published in six weeks' time, was not set up to take a view on the legality of the acts of individuals or events.
That includes whether the invasion of Iraq in 2003 was legal.
The report instead looks at the decision making behind the conflict, the consequences and whether any lessons can be learnt.
Blair, who was Labour Prime Minister from 1997 to 2007, is likely to be pressed on his role over the Iraq conflict during a scheduled appearance on The Andrew Marr Show on BBC One tonight NZT.
Jeremy Corbyn, the Labour leader, has already said he will push for Blair to be prosecuted if he is found to have broken any laws.
Asked if Blair should be charged with war crimes, Corbyn went on: "If he's committed a war crime, yes. Everyone who's committed a war crime should be.Corbyn said last August: "We went into a war that was catastrophic, that was illegal, that cost us a lot of money, that lost a lot of lives, and the consequences are still played out with migrant deaths in the Mediterranean, refugees all over the region."
"I think it was an illegal war, I'm confident about that. Indeed, [former UN Secretary-General] Kofi Annan confirmed it was an illegal war, and therefore [Blair] has to explain that. Is he going to be tried for it, I don't know. Could he be tried for it? Possibly."
Corbyn's aides signalled last week that he stood by these comments.
Reg Keys, whose son Lance Corporal Thomas Keys died in Iraq in 2003, said: "I do understand that [inquiry chairman] Sir John [Chilcot] cannot apportion blame but I hope he may suggest blame."
