"I am going to Maharashtra tomorrow to decide on BJP legislature party leader," Singh had told reporters on Sunday.
The BJP has appointed Singh and senior leader J P Nadda as central observers to choose legislature party leader, as decided by the BJP parliamentary party.
The BJP secured 122 seats in the 288-member assembly, well short of absolute majority. The Nationalist Congress Party has offered outside support, but the party is yet to take a call on it.
Former ally Shiv Sena has said it is waiting for the BJP to make the first move towards a possible reconciliation.
