National Panthers Party leader and ex-minister Harsh Dev Singh Wednesday advocated for unity among political parties to seek revival of statehood and restoration of a democratically elected government in Jammu and Kashmir. He alleged the BJP was breaking the opposition by its "divide and rule policy" to continue its "political hegemony" in the Union Territory. "Collective efforts are required to be made to ensure justice to the people of the erstwhile state reeling under the dictatorial regime of the BJP," Singh told reporters here.
