A new political party could play spoiler between India's traditional rivals in elections Wednesday in the capital.

Nearly 12 million people are expected to choose representatives to the 70-member Delhi Assembly in polls that are a significant bellwether for general elections next year.

The incumbent Congress Party and the main opposition Bharatiya Janata Party are being confronted with a new opponent this year: the Aam Aadmi Party, or Common Man's Party, led by a former tax official turned anti-corruption crusader Arvind Kejriwal.

The new party hopes to capitalize on the disillusionment with the major political parties by offering what it claims will be an honest administration which takes Delhi's pressing problems as its priority.
