The "Mr. 10%" label on Zardari was placed by the Sharifs in the 80s and , in return, the Bhuttos placed some serious charges on the Sharifs. And in their respective efforts to malign each other, the Establishment duly contributed over 3-4 decades and the charges have stuck. If you see all three players--the same three entities which PTI is targeting, they are the one who put those charges against each other. PTI was nowhere to be seen. So, logically, PTI accepts that those parties were right in their charges--that they are credible enough then. Except, of course, when anything those three entities charge PTI with, then those three entities are not credible.
