K. Sankaran Nair (1919–2015), known as Colonel Menon among his colleagues, was an Indian civil servant, diplomat and the director of Research and Analysis Wing (RAW), the apex intelligence agency in India. He served as the Indian High Commissioner to Singapore from 1986 to 1988 and was the last member of the Indian Imperial Police. He was reported to have played a crucial role in the formation of Bangladesh, through RAW operations during the Bangladesh Liberation War. His memoirs, Inside IB and RAW: A Rolling Stone that Gathered Moss, published in 2008 made news for the insider details it contained about two of the highest intelligence agencies in India. The Government of India awarded him the third highest civilian honour of the Padma Bhushan, in 1983, for his contributions to society.
