Islamabad, July 19 (IANS) With the arrest of former Pakistan prime minister Shahid Khaqan Abbasi on Thursday, the country's two former prime ministers and a president are now under imprisonment over corruption charges.

Two more former prime ministers Yusuf Raza Gilani and Raja Parvez Ashraf are making rounds of the courts over similar charges, says a report by Urdu daily Jang.
