ISLAMABAD: Pakistan’s embattled former military ruler Pervez Musharraf flew to Karachi late on Saturday to undergo medical tests, according to close aides, two days before he is due to appear in court in Islamabad. It is the first time that the former president, who will be staying with his daughter in Karachi, has left Islamabad after being indicted in a high treason case by a special court last month. Musharraf is due to appear in court in person in Islamabad on Monday in the murder case of a slain Baluch nationalist leader, or face arrest. But his aides insisted his visit to Karachi had been pre-planned. “He was planning to spend some time with his daughter there as his wife is in Dubai taking care of his ailing mother,” Afshan Adil, a close aide and lawyer told Agence France-Presse.
