The National Autit Office report that criticises the nuclear submarine programme for overspends and poor contracts today may add to the point that the Ministry of Defence has failed to learn the lessons of past mistakes, but our defence correspondent Jonathan Beale says this time changes could follow.
He says: "The criticisms will likely catch the attention of the prime minister's chief special adviser, Dominic Cummings, who wants to overhaul the way the MoD buys military equipment.
"Mr Cummings, who has been a harsh critic of defence procurement, has already held talks with Defence Secretary Ben Wallace about ways of tackling waste."
Mr Wallace recently admitted there was a shortfall in the department's budget.
In a statement the Ministry of Defence said it was carefully examining the conclusions of the report but was committed to strengthening the management of its nuclear programme.
