Like the Nehru-Gandhi family in India, the Bhuttos of Pakistan are one of the world's most famous political dynasties. Benazir's father, Zulfikar Ali Bhutto, was prime minister of Pakistan in the early 1970s.

His government was one of the few in the 30 years following independence that was not run by the army.

Born in 1953 in the province of Sindh and educated at Harvard and Oxford, Ms Bhutto gained credibility from her father's high profile, even though she was a reluctant convert to politics.

She was twice prime minister of Pakistan, from 1988 to 1990, and from 1993 to 1996.

On both occasions she was dismissed from office by the president for alleged corruption.
