David Cameron denies 'mixed messages' on Afghan pull-out

David Cameron's second day in Washington has been overshadowed by accusations from the opposition that his government has been sending out "mixed messages" over plans to withdraw troops from Afghanistan by 2015.

The prime minister, his deputy Nick Clegg and foreign secretary William Hague have all said UK forces will not stay beyond that date in a combat role.

But Mr Cameron has also said the withdrawal would be "conditions based".
