Defence Secretary Philip Hammond has urged Tory backbenchers to give his plan for recruiting more than 10,000 Army reservists a chance, instead of "throwing roadblocks".
Responding to accusations that recruitment targets for the Army Reserve have been missed, he said it was still early days and that he would not tolerate a halt in that process.
He also accused opposition parties of exploiting a Tory rebellion for political advantage.
