"It was very unfortunate that Prime Minister Manmohan Singh being a sikh has failed to provide justice to the victims of 1984 riots," said Ramdev addressing a rally in Kapurthala.
He asked people not to vote for Congress and teach them a "lesson" for failing to check the level of corruption, inflation and unemployment.
"The Congress is a sinking ship and many Congress men want to leave the it," said Ramdev.
He said that he would write to the PM after seeking public opinion and the consent of all MPs over the issue of black money stashed away in foreign banks.
Ramdev also proposed that every property should be declared as national asset after fixing a personal property and upper limit of wealth up to Rs 20 crore to check the stashing away of country's money to foreign banks.
He further said that he would not form his own political party but will go against the Congress in the Assembly elections if the party failed to bring back the black money stashed away abroad.
