Recently the Islamic Republic of Iran labelled BBC Persian Television a key tool of “soft power” being used to stir up the demonstrations which have convulsed the country since the contested presidential elections in June 2009. Thirty years ago, the Shah of Iran regarded the BBC Persian Service radio as his “enemy number one” and held it responsible for promoting the revolution of February 1979. Iranians are intrigued by the relationship between the BBC and the British Foreign and Commonwealth Office while academics, journalists and political and media analysts continue to debate the role of BBC language services around the world. What was the role of the BBC Persian Service in the Iranian revolution of 1979? Did the British Foreign Office interfere in the content of the daily broadcasts to Iran? Was the radio service a contributory force in the popular mobilization? Representatives from the BBC World Service, the Foreign and Commonwealth Office, Iranian officials and diplomats as well as independent journalists and writers who were active in that period are invited to tell their stories and debate the implications of that period. An invited audience will have a chance to ask questions. These witness accounts, which will be recorded live, will add significantly to our understanding of this crucial period in the contemporary history of Iran and the role of the BBCWS within the strategies of British public diplomacy. The event forms part of an on- going project on ‘diasporic nationalism’, part of the ‘Tuning In’ research on the BBC World Service funded through the AHRC Diasporas research programme. Speakers include Andrew Whitley and Lotfali Khonji; video-taped interviews with Lord David Owen and Fred Halliday.
