Sonia, Rahul congratulate Kejriwal on winning Delhi polls

Congress president Sonia Gandhi and party vice-president Rahul Gandhi on Tuesday congratulated Aam Aadmi Party (AAP) chief Arvind Kejriwal for his party's victory in the Delhi Assembly polls.

"Congress President Smt. Sonia Gandhi and Vice President Rahul Gandhi congratulate Arvind Kejriwal #DelhiPollResults," the official twitter account of the Congress said.

"My congratulations to Mr. Arvind Kejriwal and AAP on their victory, ppl of Delhi have chosen AAP and we respect that: Congress VP Rahul Gandhi," it added.

"Congress President Smt Sonia Gandhi spoke to Shri Arvind Kejriwal and congratulated him on the Aam Admi Party's victory in Delhi elections," it said in a series of tweets.

In a major setback for the Bharatiya Janata Party (BJP) and the Congress, the AAP won the elections with 66 of the 70 assembly seats up for grabs.

The BJP, which was relying heavily on Prime Minister Narendra Modi's popularity and had also brought in former IPS officer Kiran Bedi as its chief ministerial candidate to counter Kejriwal, managed to secure just three seats.

The Congress, which had ruled the national capital for 15 years up to 2013 and was trying to rebuild its lost ground in Delhi, has lost in all seats.
