With the Aam Admi Party putting up an impressive performance in the Assembly elections in Delhi, social activist Anna Hazare on Sunday said Arvind Kejriwal could become Chief Minister one day and warned the Congress that people would teach it a lesson in the Lok Sabha elections.

Hazare, who had refused to campaign for Kejriwal’s party, expressed happiness over AAP’s performance in the Delhi elections where Sheila Dikshit has served as Chief Minister for 15 years.

“Definitely, Delhi is the centre of the country’s politics. It is not an easy task to defeat a government, which is ruling there with just a broom in hand.

“The old parties have a lot of money. I feel happy that in such a situation, his party has emerged victorious and got 24 seats,” Hazare told reporters when asked about AAP’s performance. At the same time, he cautioned Kejriwal against allying with any party.
