You got it wrong mate, undisputed shehenshah of joor-toor is NS. Others are far -distant 2nd.
Looks like you forgot the "joor toor" of 80s and 90s by Nawaz. He will beat Salman Taseer and Zardari hands down any day!
80s?
And I dont think the PML needed any jor tors, especially in 1996 when they got more than 2/3s of majority. PPP on the other hand needed a big jor tor in 1988, 1993 though
