Shiv Sena leader Sanjay Raut on Saturday claimed that Nationalist Congress Party's Ajit Pawar was "blackmailed" into joining hands with the BJP to form government in Maharashtra.
He said Ajit Pawar might return to the NCP fold.
BJP's Devendra Fadnavis on Saturday took oath as Maharashtra chief minister, while Ajit Pawar as his deputy.
"NCP leader Dhananjay Munde has been contacted. Ajit Pawar may also return (to NCP fold). We have information how Ajit Pawar has been blackmailed and will expose this soon," Raut told reporters.
Munde, who is said to have been in touch with Fadnavis since the last few days, had gone incommunicado. He is said be supporting Ajit Pawar.
Munde was elected from Parli where he defeated his cousin and BJP leader Pankaja Munde.
"The new government was formed at 7 in the morning. In the cover of darkness only sins are committed," Raut said.
