New Delhi, Dec 8 (IANS) Social activist Anna Hazare Sunday said Aam Aadmi Party (AAP) leader Arvind Kejriwal will do good work sitting in the opposition.

"I believe that Arvind Kejriwal will do good work in the opposition and will provide right direction to the government," Anna Hazare told a news channel from Ralegan Siddhi.

"Defeating Sheila Dikshit is not an easy thing. People gave their mandate," he said.

Sheila Dikshit, Delhi's chief minister for 15 years, resigned Sunday after the Congress was routed in the assembly elections, with she herself set to lose to Kejriwal.

Dikshit submitted her resignation to Lt. Governor Najeeb Jung as the vote count showed that the Congress may not win even a dozen seats in the 70-member assembly.
