Hazare had written a letter to Prime Minister Manmohan Singh, expressing displeasure over the Central government's failure to bring in the anti-graft legislation.
The Gandhian alleged that Centre had been dragging its feet on the passage of Lokpal Bill in Rajya Sabha for last one year, because it lacked "political will".
The Centre had passed the Lokpal Bill in Lok Sabha, bowing to the public pressure in the wake of Jan Lokpal agitation in 2011.
In his reply to Hazare's letter, parliamentary affairs minister V Narayanasamy mentioned various steps taken by the government to bring in the Lokpal Bill.
Expressing his displeasure over the government's efforts, Hazare said, "correspondence has been going on for last two years but without any result. Earlier, the Centre assured that the bill will be presented in the Budget session of Parliament. The selection committee had passed it on November 23, 2012, but nothing happened even in the monsoon session."
