David Perman worked for the BBC World Service for 20 years, managing radio broadcasts in English, Arabic and Greek. His work was praised, but on one occasion he was reprimanded and then sacked. Resettled, he went on to interview the controversial Iranian Ayatollah Khomeini and was given a large budget to interview 13 world leaders. He was truly ‘a square peg’ in Bush House – the home of the BBC World Service from 1941 to 2012. But there were many other ‘square pegs’.
