Prime Minister Manmohan Singh Friday said his great regret as prime minister was that many bills had not been passed due to the "obstructionist" and "impatient" attitude of the opposition.
"The obstructionist role of the opposition increased in recent years. My great regret is that many important bills have not been passed (due to the opposition's attitude)," he told journalists on board his special aircraft while returning from a five-day trip to Japan and Thailand.
