These are conclusions of the report released yesterday by parliament’s Committee of Public Accounts.

“The Major Projects Report 2009 is the latest in a long running series of reports examining the record of the Ministry of Defence (the Department) in meeting cost, time and performance targets for its top military equipment projects which are expected to cost more than £60 billion.

Our hearing identified the serious consequences of failings in the Department’s governance and budgetary processes. Even using the Department’s own, over-optimistic estimates the defence budget is unaffordable by some £6 billion. The exact size of the gap is dependent on the assumptions one makes about future funding, but the gap could easily be £36 billion and potentially even more.”
