M. R. Akhtar Mukul (1929–2004) was a Bengali writer and journalist from Bangladesh; earned fame for Chorompotro, a radio program from Shwadhin Bangla Betar Kendra. Mukul started the program from the clandestine Shwadhin Bangla Betar Kendra, the radio station run by the Bangladesh Government in Exile in India during the liberation war in 1971 (25 March-16 December) against Pakistani armed forces. Chorompotro, meaning 'the ultimate mail', or an 'ultimatum' was the radio program. Between 25 May and 16 December 1971 Mukul broadcast the feature in 117 episodes in 206 days. In Chorompotro, Mukul used a dramatically funny voice and caricatured the positions of the military President of Pakistan Yahya Khan, the members of his government, his civilian allies like Zulfiqar Ali Bhutto, his governors in occupied Bangladesh, army generals and soldiers as well as Pakistan's international allies including the US and China. His language was full of verbal insults. In his offensive language, he used various Bengali dialects of Bangladesh as well as songs and proverbs, folk stories and jokes; and the program found popularity amongst all Bengalees including the freedom fighters, the Bengalee refugees in India as well as the general population in both occupied Bangladesh and West Bengal in India. The broadcasts remained anonymous until the final episode and the final words where he disclosed his name.
