Who is Anna?
Maybe he is a congress man who is being used to divert the attention from Baba Ramdev who had this original idea of fight against corruption (he really conducted rallies around the country). Now he has the public sentiment in his favor. Whole of this fast episode maybe staged to make Anna more popular and get a readymade leader who can make people think the way they want at any time. Now on a later date they may ask Anna to make people believe that what congress did and is doing is perfectly fine & good for people of India and we should trust them. In return they have destroyed Baba Ramdev completely who was alleged to have good relations with BJP.
