Lok Janshakti Party (LJP) chief Ram Vilas Paswan said all the former Prime Ministers from the Congress party barring Manmohan Singh belonged to upper castes, however, he does not know which caste Singh belongs to.

When asked about the Constitution (124th Amendment) Bill, which provides 10 per cent reservation in education and government jobs to economically-weaker sections of general category, Paswan said, "All the Prime Ministers from Congress party, barring Manmohan Singh as I don't know what caste he belongs to, belonged to upper castes. Why did they never think of bringing in reservation for the poor 'savarnas'?"
