David Cameron has issued a fresh call for a timetable making clear when the Chilcot report into the origins of the war in Iraq will be published.
The Prime Minister told reporters during his recent Asia trip that he wanted to see the report "as soon as possible", adding: "Right now I want a timetable".
He said: "More important than anything is thinking of the parents who lost loved ones in Iraq."
Mr Cameron spoke of meeting a woman earlier this year, who had lost her son near Basra in 2007.
"The most powerful conversation I've had about this was a mother who said to me at the Staffordshire Arboretum, when we were commemorating the Bastion Memorial Wall for Afghanistan was just, you know, it's the parents and the families who want answers.
"And for their sake, as well as for the sake of the public, we've got to get on with this.
"I can't make it go faster because it's a public inquiry and it's independent, but i do want a timetable and i think we deserve one pretty soon."
Sky News Political Correspondent Sophy Ridge says the Iraq war is still a “very controversial subject” in Westminster.
That controversy extends to the role played by former Prime Minister Tony Blair, who was in power when Britain went into Iraq in 2003.
She said Labour leadership contender Jeremy Corbyn was asked if Blair should be tried for war crimes and he replied: “If he’s committed a war crime, yes. Everyone who has committed a war crime should be.”
In July the chairman of the inquiry into what took Britain to war in Iraq in 2003 was still unable to say when the report would be released.
Sir John Chilcot has said the inquiry is making "significant progress" but he could not yet set out a timetable, further frustrating No 10's attempts to hasten the publication.
The head of the Civil Service Sir Jeremy Heywood said he had repeatedly offered to help with the process in an attempt to speed up the release of the report, which was set up in 2009 and has cost the taxpayer £10.3m.
In a letter to the chairman of the Foreign Affairs Select Committee, Sir John says the inquiry is making progress through Maxwellisation, which gives those criticised in the report the right to respond.
Tony Blair has dismissed suggestions that he is responsible for the delays.
In June, the Prime Minister wrote to Sir John expressing his disappointment there was no timetable for the release of the report.
He said for six years "those who served in Iraq or lost loved ones in the conflict have been awaiting your work".
