"I think democracy is a very valuable institution, if we play with it and undermine it, we would be great losers as a nation," he said.
"They (AAP) have been elected to power and I think power gives an opportunity, but it also gives responsibility. They must understand the responsibility that rests on their shoulders," said the senior Congress leader.
