Mr Blix served as director general of the International Atomic Energy Agency in Vienna from 1981 to 1997 and as executive chairman of the UN Monitoring, Verification and Inspection Commission from March 2000 to June 2003.

Most recently, Mr Blix has been chairman of the Weapons of Mass Destruction Commission, an independent body funded by the Swedish government that strives for non-proliferation, arms control and disarmament of weapons of mass destruction.
