A Pakistani high court is scheduled to hear a plea filed by jailed former prime minister Imran Khan and his wife, Bushra Bibi, on Thursday, challenging their convictions in the Al Qadir Trust case.

An Islamabad accountability court in January last year sentenced 73-year-old Khan to 14 years and Bibi to seven years in prison in the corruption case led by the National Accountability Bureau — the anti-sleaze watchdog.
