Britain has a spy problem, with a significant surge in threats from China, Russia and Iran in recent months. What kind of covert operations are they running? Gavin Esler sits down with former MI6 director of operations and intelligence and director of transnational threats and political risk at the International Institute for Strategic Studies, Nigel Inkster, to find out just how concerned we should be.     • “We’re seeing a significant upsurge in espionage and other forms of covert activity directed at western countries.” – Nigel Inkster  • “At the end of the day, there is always going to be a role for the human source, for secret agents, because you need to know what is going on in the minds of key decision makers… you can’t interrogate a tape recorder or a satellite.” – Nigel Inkster    We are sponsored by Indeed.
