There was no motorcade, and none of the traditional trappings of power:

the leader of India's upstart "common man party" arrived on a crowded metro train yesterday to be sworn in as chief minister of Delhi, India's capital.

Tens of thousands of supporters watched as Arvind Kejriwal, a former tax official, was anointed after a stunning electoral debut that has jolted the country's two main parties.

The emergence of Kejriwal's Aam Aadmi (Common Man) Party could give it a springboard to challenge the mainstream parties in the upcoming general election, due by next May.
