David Cameron: Afghan handover plans 'on track'

Nato leaders have gathered in the US for a summit dominated by the withdrawal from Afghanistan.

The aim of the summit is to agree on a common stance as the alliance prepares to hand over security duties to Afghan forces at the end of 2014.

Speaking in Chicago, UK Prime Minister David Cameron said that Nato plans were "on track" and that "huge progress" had been made in tackling terrorist training camps.
