The deadline for submitting nominations for the post was extended by three hours after Shiv Sena raised certain objections.
However, Chief Minister Devendra Fadnavis called upon all parties to ensure a "unanimous election" to the august post without a contest.
He said he would discuss the issue with the leaders of of the Shiv Sena and Congress to forge a consensus.
The speaker' election is considered the first big legislative test for the BJP minority government coming just before the vote of confidence in the assembly Wednesday afternoon.
BJP leaders claimed that they would easily win the speaker's elections as they are in a position to must sufficient votes.
