Nigel Inkster (born April 1952) is the former director of operations and intelligence for the British Secret Intelligence Service (SIS, also known as MI6), and is currently the Director of Transnational Threats and Political Risk at the International Institute for Strategic Studies(IISS)
Inkster was educated at Oxford and joined SIS in 1975, for which he served in posts in Kuala Lumpur, Bangkok, Beijing, and Hong Kong. He rose to become deputy to SIS chief Richard Dearlove, and was widely assumed to be in line for the top spot when Dearlove announced his departure in 2003. The selection of John Scarlett instead of Inkster was the subject of considerable political controversy.
