The anti-corruption crusader also promised stern action if the government failed to do the same and said that he would go against the government in the upcoming assembly elections in Uttar Pradesh and Hisar.
Anna Hazare before going on a Maun Vrat (vow of silence) said after he received Prime Minister Manmohan Singh's letter he was hopeful that the government would pass a strong Lokpal Bill.
"If the government brings a strong Lokpal and keeps its other promises, why should I oppose the Congress. In fact we will work with the Congress," said Anna.
Anna further rejected the fact that his team was against Congress and campaigned against Congress at the behest of RSS and BJP.
"I have only seen him (RSS Chief Mohan Bhagwat) on TV, I have never met himor spoken to him. These are all allegations. In politics political parties are ready to do anything. The Congress, BJP and RSS are together conspiring to defame Anna. I have nothing to do with the RSS or BJP," said Anna Hazare.
