Prosecutors at the International Criminal Court will examine the Chilcot report for evidence of abuse and torture by British soldiers but have already ruled out putting Tony Blair on trial for war crimes, The Telegraph can disclose.

The decision has outraged families of troops killed in Iraq who blame Mr Blair for engineering the war.

Sir John Chilcot’s report will finally be published on Wednesday and is expected to strongly criticise Mr Blair’s role in the US-led invasion of Iraq in 2003.

But in an official statement to the Telegraph, the International Criminal Court (ICC) said its prosecutors would comb through the 2.3 million word report for evidence of war crimes committed by British troops but that decision to go to war remained outside its remit.
