Arvind Kejriwal's Aam Aadmi Party (AAP) will release a "Black Paper" today in response to the White Paper on irrigation that has been prepared by the Maharashtra government. The activist-turned-politician has slammed the report which was presented to the state cabinet on Friday and practically gives a clean chit to NCP leader and former deputy chief minister Ajit Pawar who resigned following allegations of under-performance and corruption in the irrigation sector.
