Star Metro - What's at stake in Britain's Iraq war inquiry

Here are some of the likely ramifications:

- Tony Blair -

The former Labour prime minister took Britain into the US-led invasion, making the case to the public and parliamentarians, many of whom were strongly opposed.

The justification was that Iraqi leader Saddam Hussein had weapons of mass destruction (WMD), but these were never found and the intelligence was later severely criticised.

Blair's close relationship with US president George W. Bush led to accusations that he privately pledged British support for the war well before parliament agreed to it.

During the war, the International Criminal Court was petitioned to investigate alleged war crimes by Blair and his ministers relating to Iraqi civilian casualties.

The court has said it would look at the Chilcot report but noted it cannot rule on the legality of the war and could only act if British courts first refused to take up the case.

A group of MPs led by former Scottish first minister Alex Salmond is also investigating possible legal action and whether Blair could be retrospectively impeached.

In a CNN interview last year, Blair said: "I apologise for the fact that the intelligence we received was wrong."

He added: "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.

"But I find it hard to apologise for removing Saddam."

- Relatives of soldiers killed -

Relatives of the 179 British soldiers killed in Iraq had pressed for the inquiry, amid criticism of the motivation, planning and management of the conflict, and accusations that the troops were not properly equipped.

Lawyers will be scouring the report for any potential basis for legal action against Blair, other officials or the Ministry of Defence, likely based on misconduct in office or neglect of duty.

However, some relatives are reportedly boycotting the launch, already convinced it will be a whitewash.

- Military and intelligence chiefs -

The inquiry is expected to deal extensively with the failures in the military operation, from the planning of the war to the occupation, during which Iraq descended into sectarian violence from which it has yet to emerge.

"There is already general recognition that there were systemic failures in the operation after we entered Basra and the south," said Malcolm Chalmers, deputy director general of the Royal United Services Institute think tank.

He said British forces underestimated the strength of the local opposition and the determination of regional powers -- notably Iran -- to undermine the US and Britain.

Previous reports have criticised the failures in intelligence that led to the conclusion that Iraq had WMD, and how that was used by politicians -- but Chilcot could add to this.

Britain's Chief of Defence Staff Nick Houghton, who was a senior British military commander in the Iraq war, could be singled out for criticism, the Guardian newspaper reported earlier this year.

- Labour party, and parliament -

Opposition Labour leader Jeremy Corbyn, who is facing a rebellion by more than 80 percent of his MPs, is expected to use the Chilcot report to bolster his position.

The veteran socialist was strongly opposed to the war in Iraq and maintains it was illegal, while many of those trying to unseat him had supported it.

But one of his supporters, Paul Flynn, said that "parliament is on trial" over the war.

"It was not just one man; it was hundreds of MPs, three select committees of this House, the military and the press who were in favour of joining a war in pursuit of non-existent weapons of mass destruction," he said.

- US-British relations -

The report will reportedly include 29 letters sent by Blair to Bush in the run-up to the invasion, which will only be lightly redacted.

There will also be some form of record of conversations between them, as well as between their successors Gordon Brown and Barack Obama.

Diplomatic wrangling over what could be published was one of the reasons why the Chilcot report took so long.
