Starmer warns Burnham not to borrow to fund defence as he reveals £15bn plan

PM unveils long-awaited defence investment plan, which he says will mean hit to road, housing and energy schemes

Keir Starmer has warned his successor not to borrow more to pay for defence as he raided energy, transport and housing projects to plug a military spending deficit with an extra £15bn over the next four years.

The prime minister revealed his long-awaited defence investment plan (Dip) on Tuesday, after an 11-month government row that cost him a defence secretary and arguably contributed to his downfall.
