A Number 10 spokesman said late on Friday that no family of the fallen would be charged after bereaved relatives said they had been brought to tears by the "disgusting" situation.

The Telegraph had discovered that while the families were to get a free hard copy of the executive summary – which would otherwise cost £30 – they would not be given the full report.

Instead they would have to pay close to £800 for 12-volume printed report like other members of the public or read it online.

After growing anger throughout the day, a Number 10 spokesman announced: "There is no question of families of service personnel who died in Iraq having to pay for copies of the Chilcot report.”

It has not been explained how the costs will be covered, but it is understood government figures will now liaise with the Chilcot Inquiry to work out a solution.

The initial news of the price tag had infuriated the loved ones of those who died during combat and have been waiting seven years for the findings.
