Frank Gardner: Key points from government's defence spending plan

The government has published its long-delayed defence investment plan (DIP) that outlines how much money it will spend on the UK's armed forces. An additional £15bn will go on defence - a total of £270bn over the next four years - and will include spending on the nuclear deterrent and new combat aircraft. But the extra money is less than the £28bn reportedly sought by defence chiefs, and both the Conservatives and Liberal Democrats have criticised the plan as underfunded.
