"Who they were he doesn't know," Dmitry said. "There were Russian representatives and a Russian general supposedly from the internal intelligence services with whom these issues were discussed."
On Thursday, Sutyagin is to be flown to Vienna where he'll be handed off to British officials before flying on to London. His family says he plans to start a new life there but isn't overjoyed by the prospect.
"Igor is a patriot and wanted to continue to live here, that's why he sees being sent to London as trading his camp in Arkhangelsk for a camp in London, but with milder conditions," Sutyagin's brother said. "Meetings with family were limited in Arkhangelsk and they'll be limited in London as well. We won't see him often and it's unclear how we can visit him, how he can visit us, it's all uncertain."
