[holding answer 27 November 2006]:The effectiveness of the Tri-service management of the movements of troops to and from theatre is the responsibility of the Permanent Joint Headquarters and is subject to continuous review. We assess the movement of troops into and out of theatre to be working well. This has been demonstrated recently by the successive conduct of reliefs in place of forces in Iraq and Afghanistan. There are, however, occasional and regrettable delays to the movement of personnel. Every effort will be made to seek to ensure that such events are minimised.
