"A grand alliance with PDP, National Conference and Congress as partners is also an option," PDP spokesman Naeem Akhtar told PTI.
Akhtar said it was one of the options that can be explored to form a stable government in the state and also fulfil the aspirations of all the regions of the state.
The idea of such an alliance was mooted by senior Congress leader Ghulam Nabi Azad.
No political party has been able to yet muster the support of 44 MLAs required to form the government in the state.
Congress, NC and several independents have offered support to the PDP for government formation.
