With the MCD polls less than four weeks away, political parties are ready with their lists of promises, subsidies and freebies. Delhi Chief Minister Arvind Kejriwal on Saturday said the Aam Aadmi Party (AAP) will abolish the residential house tax and waive arrears if voted to power in the Capital's civic bodies. He added that industrial and commercial house tax, however, will remain the same. The city already gets subsidised power and water supply.
