A meeting of the Congress working committee is underway on Monday morning to decide on whether to support the Shiv Sena in forming the government in Maharashtra, sources said.

Sena leader Arvind Sawant, the lone party minister in the Modi Cabinet, on Monday announced his decision to quit the NDA government at the Centre.

Ahead of by-poll elections in Maharashtra, the relations between the Saffron Party and its alliance Shiv Sena gradually worsen over a series of issues majorly on forming government. As a result, Shiv Sena minister in the NDA government at the Centre, Arvind Sawant, quits as Union minister.

Hours after the BJP declined to form government in Maharashtra on Sunday, Governor Bhagat Singh Koshyari on Sunday night asked the Shiv Sena to "indicate the willingness and ability" of the party to stake claim, mounting suspense over formation of government in the state.

The BJP on Sunday slammed Congress leader Navjot Sidhu for praising Pakistan Prime Minister Imran Khan at the Kartarpur corridor inauguration across the international border and allegedly seeking to present Pakistani leadership on a higher pedestal than India's.

Further, it could think of an "alternative" if the Shiv Sena too voted against the BJP, NCP's chief spokesperson Nawab Malik said.

Attacking the BJP, Samajwadi Party supremo Akhilesh Yadav on Sunday said Moody's Investors Service cut India's credit rating outlook from stable to negative as it expected that in future too economic growth will be less and risk will rise more.

On the other hand, Shiv Sena has kept its MLAs in a hotel in Mumbai. The Congress has accused the BJP of buying and selling MLAs. According to the allegations, the BJP has offered Rs 25-50 crore.
