"The PDP president has convened a meeting of the extended core group of the party tomorrow at her residence in the afternoon," a senior PDP leader told PTI.
He said those invited to the meeting include the party MPs, former ministers, and the senior party office bearers.
This will be the first formal party meeting to be chaired by Mehbooba since the death of her father and then Chief Minister Mufti Mohammad Sayeed on January 7.
The BJP has maintained that the PDP has to make the first move by electing its legislature party leader before they can extend support to the regional party for government formation in the state.
The PDP, on its part, has said it will review the implementation of its Agenda of Alliance with the BJP during the 10-month coalition before deciding on its next course of action.
