How much should the UK spend on defence?
The Royal Navy's flagship, the aircraft carrier Ark Royal, is to be scrapped early as part of the government's defence review. How big should the defence budget be?
David Cameron is due to unveil the first strategic defence and security review in 12 years at 1530 BST.
The budget will be cut by less than 10% following a personal intervention by Prime Minister David Cameron, according to BBC Defence Correspondent Caroline Wyatt.
Should the Defence Budget be protected from larger cuts? Was Mr Cameron right to intervene? What do you think of Hillary Clinton's reaction? Should Army numbers be cut?
