The MoD will also be allowed to spend up to £500 million this year, which it expects to raise by selling Eurofighter jets to Oman. It will also be able to spend money which it has promised to recoup by renegotiating procurement contracts. Whitehall sources said the Treasury’s new “flexibility” would fill up to three-quarters of the shortfall. The remaining gap – around £200 million – will be filled through unprecedented new cost controls imposed on the MoD by the Treasury. Those restrictions could mean new Chinook helicopters promised to the Army are delayed by several years.
