The head of the inquiry into the Iraq war is to face MPs today to explain the delays in the final report, more than five years after the probe was launched.
Sir John Chilcot will face questions from MPs amid fierce criticism of the delays.
The inquiry chairman will appear before the Foreign Affairs Committee to discuss the process and "obstacles which remain". Prime Minister David Cameron has been among those expressing frustration that the report has yet to be finalised.
Roger Bacon, who lost his son Matthew in 2005 during the Iraq conflict, said he is desperate for answers about why the UK went to war.
Sir John Chilcot will write a letter to the Prime Minister explaining why his inquiry will not be able to report until after the election.
