Jailed former Prime Minister Imran Khan’s party has expressed concern about the health of his wife Bushra Bibi and claimed that there was a "serious threat" to her life and the “fascist regime” in Pakistan was denying her medical aid.

Bushra Bibi, 49, is imprisoned at Khan's Bani Gala residence here after an accountability court sentenced the couple to 14 years in jail in the Toshakhana corruption case last month.

Khan, 71, is lodged at the high-security Adiala Jail in Rawalpindi. Both of them have been convicted with multiple years’ sentences in the Toshakhana expensive gift case and the iddat case which declared their marriage as un-Islamic.

Bushra has already petitioned the Islamabad High Court on February 6 against authorities' move to declare her residence as sub-jail and requested to move her to the Adiala Jail citing “potential security issues”.

The concern expressed by Khan’s Pakistan Tehreek-e-Insaaf (PTI) party is a result of a claim by the party’s legal coordinator Mashal Yousafzai that Bushra’s life is in danger and she needs immediate medical attention.
