BJP leader Arun Jaitley said the recent history has not been kind to Rao, who is largely credited with ushering in the era of privatisation and limiting government control of the economy, and the "good turning point" in the economy came when he became PM after "wasted" 70s and 80s.
"For Vajpayee as a BJP prime minister to move ahead with reforms was relatively easier because it was a natural part of his party's ideological thinking but for a man (Rao) who belonged to a party (Congress) which did believe in regulation to break the trend...," he said.
The compliments for Rao from BJP came a day after former Union Minister K Natwar Singh said Rao as a PM felt "insulted" by Sonia Gandhi as she "felt" that the trial of Rajiv Gandhi's killers was not proceeding fast enough.
"How often do I see her? It is a question of my self respect. Her attitude is affecting my health. How many times do I have to be insulted?" Rao had told Singh, his colleague in the ministry who was also then said to be close to the Gandhi family.
