Skripal provided information to intelligence agencies after arriving in UK - daily

Former Russian military intelligence (GRU) Colonel Sergei Skripal continued to provide information to western intelligence agencies after arriving in the UK in 2010, the Financial Times daily said on Friday citing security officials.

According to one former senior security official, Skripal was still valuable for "friendly’ spying agencies."

"There was interest from friendly foreign services after he was released in the spy swap," the source said cited by the Financial Times. "He was useful for a limited period."

In particular, Skripal might have been able to inform western intelligence agencies about "how they [Russians] infiltrate the west, how they recruit, how to counter intelligence."

"That was an ongoing use," a second official told the daily.

In 2004, Russia’s Federal Security Service (FSB) arrested Skripal and later on, he was sentenced to 13 years in prison for high treason. Six years later, the former colonel was handed over to the US as part of a swap involving espionage suspects. In the same year, Skripal arrived in the UK and settled there.
