More British defence assets must be sold in order to fund front line troops, the Defence Secretary Michael Fallon has warned.
Fallon blamed the "chaotic legacy with a £38bn budget black hole" for the necessity of further cuts to defence.
Sales of land and buildings have raised almost £380m so far, but Fallon shall insist the "job's far from over" in a speech to the Institute of Government.
"We need to ask more questions about our assets: How many airfields do we need, how many cars and vehicles do we need, and how do we go further in rationalising our defence estate?"
Speaking of a need to make the Ministry of Defence's portfolio "sweat", he continued: "With continuing demands on our resources, with the cost of manpower and equipment rising and with competition from emerging nations, increasing efficiency in defence cannot be a one-off.
"Every year we should be looking to take out unnecessary cost, to improve productivity, and to sweat our buildings and land so we can better support the front line."
