I hear that families of British soldiers killed during the Iraq War are threatening to take legal action against Sir John Chilcot if his Report isn't published by the end of the year.
He has said publication of his report has been delayed to allow those who have been criticised to respond.
Lawyers for the soldiers' families claim he acted unlawfully by refusing to set a deadline for publication.
The five-member panel, led by Sir John, began its work in 2009 and held its last hearings in 2011.
The inquiry took evidence from hundreds of witnesses, including former Prime Minister Tony Blair, and is set to cost taxpayers £10m.
The delays, to allow those who might face criticism in the report to argue their case, have led to frustration among some of the soldiers' families.
'Black cloud'
Lawyers acting for 29 of them have written to Sir John calling for him to set a deadline for witnesses to respond and to promise the report will be published by the end of the year or they will take their case to the High Court.
Should people who were to be criticised in the report been given this chance to 'argue their case' prior to the report's publication.
Is 4 years an excessive time period for pulling stuff together in view of the complexities of the matter?
