Aam Aadmi Party (AAP) chief Arvind Kejriwal on Saturday hit out at the Bharatiya Janata Party (BJP) over power crisis in the national capital. br br While slamming the BJP, the former Delhi chief minister asked the party to take immediate action to normalise the power supply.br Kejriwal's reaction comes after the national capital on Friday reeled under massive power cuts ranging from two to ten hours as a number of major electricity transmission lines tripped due to technical snags. br br Delhi Lt Governor Najeeb Jung said many areas will continue to face planned blackouts for a few more days as repairs to the power towers and lines which were damaged in the storm that hit the city last week are taking time.
