KARACHI - MQM chief Altaf Hussain on Thursday demanded of President Asif Ali Zaradari, Prime Minister Yousaf Raza Gillani and the federal cabinet to take back the recent hike in the power-tariff and resolve the issue of loadshedding in the country on emergency basis. In his statement issued on Thursday, he said that the KESC has decided a 70 per cent increase in the power-tariff for domestic and industrial use in the metropolis without solving issue of loadshedding. He said that due to prolonged power outages, industrial and business activities in the country were severely disturbed compelling traders and common people to come on the streets in protest. Altaf also urged President Asif Ali Zardari to order the KESC to take back its decision of increasing power-tariff and adopt concrete measures to resolve the issue of prolonged load-shedding.
