Nagpur, Dec 10 (IANS): Signalling a stormy start to the winter session of the Maharashtra assembly, the opposition took out a silent black flag procession to the legislature here Monday morning.

Legislators from all opposition parties -- Shiv Sena, Bharatiya Janata Party (BJP) and Maharashtra Navnirman Sena -- carried placards and banners against the re-induction of Nationalist Congress Party (NCP) leader Ajit Pawar as the deputy chief minister.

Pawar, who quit his post Sep 25 in the wake of an alleged Rs.20,000 crore irrigation department scam, rejoined the cabinet last week, raising the opposition's heckles.

The opposition has alleged that Pawar's swearing-in was "unconstitutional" and has demanded a special investigating team to probe the alleged scam.

The opposition has also questioned the 'White Paper' on the irrigation department and the 'clean chit' given to Pawar that enabled his return to the ministry.

Opposition leaders Eknath Khadse (state assembly) and Vinod Tawde (state council), both from the BJP, have termed the report a "black paper" and threatened to disrupt the house.

The opposition also plans to target several ministers of the ruling Congress-NCP coalition for their alleged involvement in various scams and irregularities.
