New Delhi, Jan 31 (ANI): Reacting to BSES' threat of 8-10 hours of power cut in central and eastern Delhi, BJP Spokesperson Capt Abhimanyu slammed the AAP government and said that the party promised the people of low power tariffs but any promise should not come in the way of the city's development and progress.
