[custom_adv] BBC Persian is the Persian language radio station and TV operated by the BBC which conveys the latest political, social, economical and sport news relevant to Iran, Afghanistan, and Tajikistan, and the world. Its headquarters are in London, United Kingdom. [custom_adv] The BBC first started a Persian radio service during World War II on 29 December 1940, encouraged by the Foreign Office, as part of its Empire Service. The government reasons for prioritising this was concern that the Iranian king, Reza Shah Pahlavi, was sympathetic to Nazi Germany. [custom_adv] Following the Anglo-Soviet invasion of Iran in August 1941, the Foreign Office encouraged broadcasting about king's autocratic style and republican systems of Government. [custom_adv] The Persian Service continued after the war as part of the BBC General Overseas Service, with more editorial independence from the UK government. However the risk of the Iranian nationalisation of Anglo-Persian Oil Company created an exceptional circumstance causing the Foreign Office to issue memorandums of advice and lists of points to make to the BBC, and the amount of broadcasting more than doubled. [custom_adv] This caused many Iranians to believe the Persian Service was not independent, and an advisor of Prime Minister Mohammad Mosaddegh said the "BBC was the voice of British imperialism and we did not trust it". [custom_adv] The British government used the BBC's Persian service for advancing its propaganda against democratically elected Prime minister of Iran Mohammad Mosaddegh and anti-Mosaddegh material were repeatedly aired on the radio channel to the extent that Iranian staff at the BBC Persian radio went on strike to protest the move. [custom_adv] The BBC was at times even used directly in the operations, sending coded messages to the coup plotters by changing the wording of its broadcasts.In a documentary Cinematograph aired on August 18, 2011 on the anniversary of the coup, BBC Persian channel admitted for the first time to the role of the BBC Persian radio as the propaganda arm of the British government in Iran. [custom_adv] "The British government used the BBC Persian radio for advancing its propaganda against Mosaddegh and anti-Mosaddegh material were repeatedly aired on the radio channel to the extent that Iranian staff at the BBC Persian radio went on strike to protest the move" the Cinematograph narrator said. [custom_adv] The Cinematograph also quoted a classified document going back to July 21, 1951 in which a Foreign Office official thanked the British ambassador for his proposals that were followed to the word by the BBC Persian radio to strengthen its propaganda against Mosaddegh. [custom_adv] “The BBC had already made most of the points which you listed, but they were very glad to have an indication from you of what was likely to be most effective and will arrange their programme accordingly,” the document shown in part on the program read. [custom_adv] “We should also avoid direct attacks on the 'ruling classes' since it seems probable that we may want to deal with a government drawn from those classes should Mosaddegh fall,” it added. The document further stressed that the Foreign Office “shall be grateful for comments on the propaganda line we have proposed”. [custom_adv] In the years before the revolution, the BBC Persian Service became highly trusted and liked by listeners, and gained mass appeal beyond intellectuals and the Iranian diaspora.
