Amour,
Again PPP of ZAB and PML (N) of NS evolved as political parties. But MQM and Chaudhries have continued to be B team of dictators. MQM is not even a national political party but a pressure group and instrument of estabilishment to topple any elected government. They also wants to rule by hook or crook because in real democracy this ethinic party has no chance to rule over masses. They can only rule on the shoulders of dictators.
