Maken released a 'charge sheet' and a 'charter of demands' on the completion of 100 days of BJP-ruled municipal corporations, and said Congress will launch an agitation over "betrayal" by the BJP.
He also alleged that the "tussle" between BJP and AAP government in Delhi has "held up" works at the ground level in the MCDs.
The BJP routed the AAP and Congress, winning 181 of the 272 wards in South, North, and East Delhi Municipal Corporations, in the civic body elections held in April.
Congress will mount pressure on the corporations in its "Pol Khol" (exposure) campaign as the BJP has "not fulfilled even a single promise" made to the people during the municipal corporation elections, he said.
