NEW DELHI: The leader of a new political party that pledged to uproot corruption from Indian politics has been sworn in as the chief minister of India's capital.

Aam Aadmi, or Common Man's Party, won 28 of Delhi's 70 assembly seats in elections held earlier this month. It paved the way for its leader Arvind Kejriwal to take office Saturday.

The party is being supported by the Congress Party, which had ruled Delhi for three terms.

Kejriwal is a former civil servant and anti-corruption crusader who campaigned to rid the Delhi government of graft and inefficiency.

Tens of thousands of people crowded a major park in central Delhi to witness Kejriwal and six other ministers take over the reins of the capital city.
