A former British soldier who is facing spying charges has admitted escaping from a London prison by clinging to the underside of a delivery truck.

Daniel Khalife, 23, changed his plea to guilty on Monday, part-way through his trial at London’s Woolwich Crown Court.

He continues to deny violating Britain’s Official Secrets Act by collecting information useful to an enemy — namely Iran — as well as breaching the Terrorism Act and planting fake bombs at a military base.
