Imran Khan, who played 88 Tests for Pakistan and led them to their sole World Cup triumph, suffered head and back injuries when he fell from a riser lifting him to a platform for a campaign speech in the eastern city of Lahore.

Messages of support from the cricket world poured in for Imran, who doctors said was making "steady progress" at the city's Shaukat Khanum hospital and was expected to make a full recovery.
