Wadettiwar has been rewarded with the post - enjoying a Cabinet Minister status - for preventing the Congress's total elimination in the state after the May Lok Sabha elections.
The Assembly LoP post has been vacant after Radhakrishna Vikhe Patil left the Congress and was made a minister in the Devendra Fadnavis cabinet.
The Maharashtra CM said that his government has already started planning for another term, and, hence, the cabinet expansion should be seen as an attempt to build a new team for another five years.
Vikhe Patil had quit the CLP and the party after his Sujay had joined the BJP and won from the Ahmednagar Lok Sabha seat.
The BJP is expecting a large number of leaders, primarily from the Congress and the NCP, to join the party in the coming days. The induction, however, is unlikely to be an easy affair for the party.
In a clear sign that all was not well with the party, a Congress MLA from Sillod, near Aurangabad, was suspended during the recent general elections for anti-party activities.
Vikhe-Patil had sent his resignation letter to Congress President Rahul Gandhi a few weeks ago, but a decision on it was pending.
The Vikhe Patil senior is working behind the curtains, they said, adding that the Congress leader is in touch with the supporters of his father late Balasaheb Vikhe Patil in Rahuri, Parnerand other ar
The senior Vikhe Patil was unavailable for comment, but his close aides rejected suggestions about the Congress leader switching sides and joining the BJP.
It was said that Vikhe-Patil has written to party president Rahul Gandhi requesting him to decide upon his resignation.
Radhakrishna Vikhe Patil is the Leader of Opposition in Maharashtra Assembly but his son Sujay Vikhe Patil joined BJP.
The NCP has been contesting the Ahmednagar-South Lok Sabha seat for around 20 years now and of these the party has lost the seat for last three terms in row.
The leader of opposition in the Maharashtra Legislative Assembly reiterated that the Congress has not held talks with the MNS for a pre-poll alliance.
Mahajan, the state's Water Resources minister and Jamner MLA, told PTI that he would be visiting Ralegan Siddhi again on Monday to hold talks with the anti-graft crusader.
The state Cabinet is in the process of placing the report before the House and taking other appropriate steps, said Additional Government Pleader Abhinandan Vagyani.
