The jury delivered their verdict after 23 hours of deliberations, convicting him of breaching the Official Secrets and Terrorism Acts.
The 23-year-old, who’d already admitted escaping from Wandsworth prison last year, was cleared of carrying out a bomb hoax.
Reporter Shamaan Freeman Powell was in court for the verdict.
He’ll be sentenced at a later date.
Commander Dominic Murphy, Head of the Met’s Counter Terrorism Command said: “The threat to the UK from states such as Iran is very serious, so for a soldier in the Army to be sharing sensitive military material and information with them is extremely reckless and dangerous.
“Khalife claimed that he wanted to help the UK’s security by becoming a so-called ‘double-agent’ but the reality we uncovered is that he simply put UK security at great risk by what he was doing.
“Then, when he was in prison awaiting trial, he escaped and went on the run. But thanks to some brilliant police work – here in the Met, but also across the country – coupled with the fantastic support of the public, we were able to find and arrest him to make sure he faced justice.
“I’d like to praise all those who worked on this investigation – those who looked into Khalife’s activity in sharing information with the Iranians, but also the many colleagues from agencies and police forces who assisted us when he was at large.
“I hope this serves as a warning that the illegal sharing of information in this way will be treated extremely seriously by security services and police and we will use the full force of the law against those who put the UK’s security at risk.”
