"It must be stopped. This (Padma awards) is only for a fistful of people who live close to the system (government)," he told reporters, noting that previous 'Janata Parivar' regimes had not given away these official honours to anybody.
He said then President A P J Abdul Kalam had sent a note to then Prime Minister Atal Bihari Vajpayee about "irregularities" in the awards and added that nobody from SCs, STs, minority and farmer communities was given these honours this year.
The socialist leader had sparked a row at an event in Mumbai last week where he alleged that Padma awards were given only to the "dishonest" and those from the upper echelons of society.
He said discrimination against the social and economically backward people had existed for long but it had crossed all limits this year, the first year of Narendra Modi-led BJP government.

Yadav, however, refused to single out names and even added that some of them may have deserved the awards but added that majority of people had been ignored.
"I, nevertheless, welcome this debate. No country practices so much discrimination as we do. What I have said is not new and have long been our stand," he said.
These awards were not given during the Janata Party government, which had come to power in 1977, and the United Front dispensation, which took power in 1991, he said.
Yadav also hit out at the RSS for its charge that 'Janata Parivar' was promoting untouchability against the Modi government and did not treat people from SCs with dignity, alleging that discrimination against Muslims and Christians had increased since BJP came to power.
