Meanwhile, NCP chief Sharad Pawar said his party will take a decision pertaining to government formation in Maharashtra only after holding discussions with Congress.
He also took a dim view of the governor giving 72 hours to the BJP to stake the claim, but just 24 hours to the Uddhav Thackeray-led party.
On November 10, Maharashtra Governor Bhagat Singh Koshyari had invited Shiv Sena to inform him if it could form government
The Sena, the second largest party in the 288-member House after the BJP (105), has time till 7:30 PM on November 11, to stake the claim
"The Sena will have to inform the governor about its stand by Monday (November 11) evening 7.30 pm," a Raj Bhavan official said
"Good luck to the Shiv Sena if it wants to form government in Maharashtra with the support of the Congress and NCP."

As no party had come forward to form the government, the governor decided to explore the possibility of formation of government on Saturday
The governor should ensure that the BJP has the numbers to prove its majority, and also see that there is no horse-trading if the BJP decides to take a floor test, the NCP spokesperson said.
