The Election Commission has formally registered social activist Arvind Kejriwal’s Aam Aadmi Party (AAP) as a political party.

Informed sources said a formal letter to this effect was sent to the AAP recently.

This will pave the way for it to contest elections to the 70-member Delhi Assembly whose term ends on December 17. The polls are expected in late November or early December along with those for the Assemblies of Chhattisgarh, Madhya Pradesh, Mizoram and Rajasthan.

The AAP has begun an intensive campaign against the Sheila Dikshit government targeting it on “inflated” power and water bills.

During the Delhi polls, it may get a one-time concession of choosing a common symbol from among the free symbols.

Mr. Kejriwal, a former member of the India Against Corruption movement, founded by social activist Anna Hazare, launched the AAP on November 26, 2012, after he fell out with the latter.

The AAP has a 23-member national executive and Mr. Kejriwal is its convener.
