A final push on Saturday brought IUML on board. The party’s high-level committee resolved that helping establish a democratic govt is a vital democratic duty to prevent political instability in the state.“The expectations of the general public, and particularly the Muslim community, are for the establishment of a democratic govt. This decision is taken to preserve the traditions of Tamil Nadu and avoid the unwelcome prospect of President’s Rule,” the party said. IUML emphasised that it has been a long-standing partner of DMK and would continue its alliance with the DMK-headed bloc.
