Tony Blair has apologised for aspects of the Iraq War, sparking claims of attempted "spin" ahead of the Chilcot Inquiry findings.
The former British prime minister used a US television interview to express regret over the failure to plan properly for the aftermath of the 2003 toppling of Saddam Hussein and the false intelligence used to justify it.
"I apologise for the fact that the intelligence we received was wrong," he told CNN.
"I also apologise for some of the mistakes in planning and, certainly, our mistake in our understanding of what would happen once you removed the regime."
Asked by host Fareed Zakaria if the Iraq War was "the principal cause" of the rise of Islamic State, he was reported by the Mail on Sunday to have conceded: "I think there are elements of truth in that."
