Sir Keir Starmer passed the buck to Andy Burnham on defence yesterday after short-changing Britain's military.After months of delays, the Prime Minister published the Defence Investment Plan (DIP), only to be told it was not enough to protect the country.He said the package of an extra £15billion over four years would give the Armed Forces the resources needed to deter a Russian attack.But the plan began unravelling last night after it emerged only £10.3billion in savings had been identified, meaning it contains a £4.7billion black hole Mr Burnham will have to fill in his Budget this autumn.Despite the growing military threat, the Ministry of Defence must find £10.7billion in efficiency cuts to help fund the package. No date was set for raising defence spending to three per cent of GDP – which is widely seen as the minimum.In an extraordinary statement, Defence Secretary Dan Jarvis told MPs the package was too little at a time of global insecurity.He suggested more money may be available at a spending review next year – another decision for Mr Burnham to make. Sir Keir Starmer finally published the Defence Investment Plan (DIP), but has been told it is not adequate to protect the country
