Nelson Mandela's "Long Walk to Freedom" was among a collection of books in jailed former Pakistan Prime Minister Imran Khan's cell, according to details of his prison living conditions that the government submitted to the Supreme Court on Thursday.

Khan complained to the court last week that he was being kept in solitary confinement without access to his lawyers.

The government submission seen by Reuters contained a list of family and friends, lawyers and party members who have seen Khan since he was jailed in August last year.
