Hazare also said there was a delay in undertaking a countrywide tour as he had recently undergone a cataract surgery.
"But now we have decided that the countrywide tour will begin in January, from the place where Jaiprakash Narayan launched his movement," he said.
"The battle for Jan Lokpal and corruption-free India will begin at the Gandhi Maidan in Patna in January," Hazare said in a statement.

A meeting of 10 technical experts was held in Ralegan Siddhi on October 14 to use technology for building a countrywide organisation, he said.
"The time for 'parivartan' (change) has come in this country," Hazare said.
