Meanwhile, union government on Tuesday announced its commitment to pass Jan lokpal bill.
Union minister V Narayanasamy made the announcement that the government is committed to pushing through the legislation - the Lokpall Bill - in this session of Parliament which ends on December 20.
However, Anna Hazare has decided to go ahead with the strike.
In the chilly 6 degrees Celsius temperature sweeping Maharashtra's Ahmednagar district, Hazare went on his usual morning walk and then started his hunger strike near the Yadavbaba temple in the village, under the banner of his new organization, Jantantra Morcha.
The Jan Lokpal Bill, also referred to as the Citizen's Ombudsman Bill, is an anti-corruption legislation drafted by civil society activists, seeking appointment of an independent panel to investigate cases of corruption.
