World's largest democracy all set for Lok Sabha battle

"The UPA will surprise everyone," spokesperson Abhishek Singhvi told IANS. "With our known allies and a few others, we will easily form the government."

Analyst Mukherjee pointed out that one key factor in this election was the Aam Aadmi Party (AAP) -- which is ranged against everyone else.

"It is a new political phenomenon where an anti-corruption movement has become a party," she said. "It is a party with a different background with all kinds of people in it."

The AAP, which ruled Delhi for 49 days until Feb 14, has pitted its leader Arvind Kejriwal against Modi in Varanasi in Uttar Pradesh.

Political analyst Pradip Dutta admitted that the BJP had a much larger lead over the Congress but added that he does not see "a Modi wave" talked about in the media.
