Tory backbencher Mark Pritchard has said that Philip Hammond could expect strong support from Conservative MPs over his stance to curb cuts to defence.
"Defence cuts have gone far enough," he said.
"There will be zero political support from Conservative backbenchers for any additional cuts beyond those already announced in the SDSR.
"The Treasury needs to look elsewhere for additional savings."
