Business of the House

In welcoming the 14 March debate on Trident on behalf of the shadow Defence Ministers, may I ask the Leader of the House whether he will guarantee that there will be no intrusion by statements on the time for that debate? Will there be protected time—six and a half hours—for that debate? Does he agree that it would send the wrong signal about the importance of this as a defence issue for the Defence Secretary to be relegated, as appears to be the case, to winding up the debate, rather than presenting the case, which he is perfectly capable of doing?
