ISLAMABAD: Upon his return from Saudi Arabia, Pakistan Tehreek-i-Insaf (PTI) Chairman Imran Khan once again trained his guns on former chief justice Iftikhar Chaudhry and Justice (retd) Khalilur Rehman Ramday, alleging them of supervising rigging carried out during the May 2013 General Elections.

"Iftikhar Chaudhry and Justice (retd) Ramday controlled the returning officers ... both of them should be tried under Article 6," the PTI chief said, while talking to reporters in Islamabad on Saturday.

Speaking on the former chief justice's Rs20 billion libel notice, Imran said he was waiting for Iftikhar Chaudhry to face him in the court. "Iftikhar Chaudhry is a traitor to democracy, I will prove this in the court," he said.

"How did it happen that PML-N grabbed 6.8 million votes in 2008 elections and in 2013 they ended up with more than 15 million votes," questioned the PTI chief, alleging that this happened because of the rigging carried out by returning officers under the supervision of the former chief justice.

This is not the first time Imran has levelled allegations against Chaudhry and Ramday. Last year in August, the PTI chief had named Iftikhar Chaudhry, Khalilur Rehman Ramday, former caretaker chief minister of Punjab Najam Sethi and officials of the Election Commission of Pakistan (ECP) as having played a role in rigging the 2013 polls.

Later in October, after dismissing allegations as baseless, Ramday had send a legal notice to Imran for defaming him and had demanded an apology.
