Former prime minister of Pakistan Imran Khan on Tuesday claimed that his wife lady Bushra bibi was poisoned at his private residence, which was turned into a sub-jail. Khan said that the army chief should be held responsible if anything happens to her. During the proceedings of the 190 million pound Toshakhana corruption case at Adiala Jail, the Pakistan Tehreek-e-Insaf (PTI) leader informed Judge Nasir Javed Rana about an alleged poisoning attempt on the former first lady.
