A court in Pakistan has rejected an appeal by former Prime Minister Imran Khan and his wife to release them from prison. Khan and his third wife Bushra Bibi asked an Islamabad court to suspend their seven-year jail terms - for what was ruled an illegal marriage. The couple were found guilty of violating Islamic law by failing to observe a required interval after Bushra divorced her previous husband. Khan has been imprisoned on a range of convictions since August. He maintains the cases are politically motivated, and aimed at derailing his return to power in elections in February.
