you as an outsider can whine abt MQM, but the best eras of Karachi were when MQM was allowed authority and was given Karachi funds to manage the city. Be it MQM or JI or any karahci based party, they have proven their merits, but the city rots under state control which fails to devolve authority to people of karachi.
The fault lies not in MQM but the pakistani state itself.
if you wanna compare london and Karachi then compare by all measurements and not just london shutdown can make huge loss for UK, blah blah.
London has a mayor who runs the city, do we have the same system in Karachi?
