'Why I want to hear Blair give evidence again'
Tony Blair is returning to the Iraq war inquiry to face questions for the second time.
The former prime minister is likely to be asked about discrepancies between the evidence he gave last year, and other witness statements.
The inquiry is also thought to be interested in the exact details of what he discussed with George W Bush in the run-up to the invasion, but correspondence between the two former leaders is not going to be made public.
Peter Brierley's son Shaun died soon after being deployed to Iraq in 2003.
