Lahore : Pakistan Muslim League-Nawaz (PML-N) Senator Pervez Rashid has blamed Imran Khan for targeting the PML-N and its leadership under a covert plan to benefit the PPP. While talking to TheNation on Saturday, he said the rising popularity and strength of the PML-N is a big worry for Asif Ali Zardari, who has pitted Imran Khan against the party and its leadership to tarnish their image and weaken them.
