That's a good point. MQM has not started the "within the family" top leader yet.
However the issue at hand is relatively simple. Why do our political leaders treat their parties as "Jagirs" and estates? From that perspective MQM, PML-A B C D N O P Q, PPP, ANP etc etc. all are the parties with "president-for-life" gods (with small g) at their top.
These poor things never understood, that it is better to change the party chairman every two years. There must be a "retirement" time for AZ, NS, Asfand, Imran, Qazi, and Altaf etc. etc.
If they don't leave, their parties will remain "undemocratic jagirs", then how can we ever expect that such parties will maintain democratic traditions in the country?
Party Head Person term should be for 3 years. He/she can be selected for 2 consecutive terms (6Years) but after serving 6 years has to wait 6 years before he can run again. He can't be elected for more than 4 terms.
