Tomorrow's protest at Jantar Mantar is also likely to see Ramdev announcing his strategy with regard to the 2014 General Elections.
The one-day fast to demand bringing back blackmoney stashed away abroad and against corruption and corrupt system will have its echo in the state capitals as well with Ramdev's Bharat Swabhiman Andolan organising protests.
Team Anna members Arvind Kejriwal, Manish Sisodia and Gopal Rai are expected to join Hazare and Ramdev in the fast.
It is also keenly watched whether retired Army chief Gen V K Singh, who had locked horns with the government on various issues, would attend the protest.
The association with Ramdev had in the past created ripples in Team Anna with a section remaining opposed to have any truck with the yoga guru as he is facing corruption charges.
Ahead of the fast, both Hazare and Ramdev have stepped up their attack on Prime Minister Manmohan Singh. Hazare had said that Singh has lost faith in government while Ramdev alleged that the Prime Minister was not "politically honest".
Before sitting on the fast, both the activists will go to Rajghat, the memorial of Mahatma Gandhi.
A senior police official said they have made elaborate arrangements. Besides Delhi Police personnel, 20 companies of paramilitary forces will be deployed in the area.
