Malik Riaz is on record to have said that even if he has to spend his entire fortune, he would do it to bury Choudary Nisar's politics. Its because Chaudary Nisar is against Malik Riaz's criminal ways to usurp land from poor people.
Nisar on the other hand has total control over patwaris etc in Pindi, which greatly irks Malik Riaz as Nisar has many a times created troubles for Malik Riaz.
Everyone knows that Malik Riaz and Zardari are bed fellows. Riaz was the only person who had unlimited access to the Presidency during the time of Zardari. It was Zardari who invited Malik Riaz to khi, and hence Bahria Town Karachi project. In addition to this, Bahria Town has now future plans of launching Bahria Town projects in Hyderabad and Sukkur.
Nisar would have been a great addition to PTI, if only he would not have launched the Islamabad operation. With him and Sheikh Rashid on PTI's side, PTI would have wiped out PML N from Pindi Division. Is it too late now ? time will tell.
