Apart from other party leaders, BJP's Devendra Fadnavis and NCP's Sharad Pawar also paid rich tributes to the Shiv Sena founder earlier in the day.
Maharashtra came under President's Rule after the BJP, Shiv Sena and NCP indicated they were not willing to form a government.
Top leadership of NCP, Congress and Shiv Sena is in constant huddle to explore the possibilities, still a concrete roadmap seems elusive. NCP has time till 8:30 PM today to give the letters of support to Governor.

Although, Raut did not confirm whether Aaditya Thackeray or Eknath Shinde will be the party's chief ministerial candidate but added, "the party chief (Uddhav Thackeray) is capable of taking this decision."
Even after getting the required numbers to form the government, there has been a delay in cobbling up a coalition as Shiv Sena has insisted that the two parties had a '50-50' power-sharing agreement before the elections.
