Pakistan's former Prime Minister Imran Khan, who is currently in jail, has submitted a petition to the Supreme Court, requesting bail in the cipher case. He challenged the Islamabad High Court's previous rejection of his post-arrest bail pleas related to the case, stated a report in PTI. 

According to the report, Khan (71), who was arrested in August following a case filed against him by the Federal Investigation Agency, was accused of disclosing a secret diplomatic cable (cipher) sent by the country's embassy in Washington in March last year.
