He was initiating a discussion on the motion of thanks to the President's address.

"There are several centres of power. It is really disturbing. We have a prime minister who has great competence without authority. We have authority but there is no competence," Singh said.

The political developments in Jharkhand, Goa and Bihar indicated there is a 'great erosion' of institutions, he said.

"If institutions are rendered inoperative or weak, we are guilty of very substantial and substantive wrong. It is saddening."

He regretted that a senior member of the Union cabinet was not aware of the political happenings in the country. "If they do not know what is happening, how will they do the right thing?" he asked.

The happenings in the last few weeks indicated there is no unity in the ruling United Progressive Alliance. The alliance was neither united nor progressive, he remarked.
