Devendra Fadnavis was unanimously elected as the Maharashtra BJP legislature party leader at its meeting here on Wednesday, paving the way for his appointment as the chief minister.
The swearing-in ceremony will be held in Mumbai on Thursday in the presence of Prime Minister Narendra Modi.
Fadnavis' name was finalised for the top post at the BJP's core committee meet held here ahead of the legislature party meeting, sources said.
Bharatiya Janata Party (BJP) leader Sudhir Mungantiwar said leaders of the Mahayuti coalition will meet Governor C P Radhakrishnan at 3.30 pm on Wednesday to stake a claim to form government.
Union minister Nirmala Sitharaman, former Gujarat Chief Minister Vijay Rupani were present at the BJP legislature party meeting held at the Vidhan Bhawan in Mumbai.
The BJP had appointed Sitharaman and Rupani as central observers for the meet.

Several Union ministers, and 19 chief ministers and deputy CMs of various states are also expected to attend the ceremony.
BJP leader Prasad Lad has said the ceremony will be a "historic moment" for Maharashtra.
"The event will be telecast live across the state wherever LED screens are available," he said.
There are indications that the distribution of portfolios among the three allies might not be a smooth process.
Sena leaders on Monday said that as per the "convention" of alliance politics, their party should get the home portfolio if the CM post went to the BJP.
