According to a report published by Express Tribune, Pakistan Muslim League-Nawaz (PML-N) leader and lawmaker Mohsin Shahnawaz Ranjha submitted the reference to the commission, contending that Imran Khan did not declare the gifts received from the Toshakhana in his assets declaration.
He argued that the PTI chief should be disqualified under Article 62(1)(f) of the Constitution.
Article 62(1)(f) says: "A person shall not be qualified to be elected or chosen as a member of Majlis-e-Shoora (Parliament) unless [...] he is sagacious, righteous and non-profligate, honest and ameen, there being no declaration to the contrary by a court of law."
The report further said that National Assembly Speaker Raja Pervaiz Ashraf is also expected to send the Toshakhana reference against Imran Khan to the ECP soon.
Responding to the Toshakana controversy in April, the former premier Imran Khan had said that those were his gifts, so it was his choice whether or not he kept them. "Mera Tohfa, Meri Marzi [my gift, my choice]," he said.
