In December 1970 Pakistan held its first democratic elections since gaining independence from British colonial rule in 1947. The elections led to war, the break up of Pakistan and the creation of a new country, Bangladesh. Farhana Haider has been speaking to the economist and leading figure in the Bengali independence movement, Rehman Sobhan, about the historic elections and their aftermath.
