Indian Prime Minister Narendra Modi has called up Aam Aadmi Party leader Arvind Kejriwal and congratulated him on his thumping victory in Delhi.
The leader of India's ruling Bharatiya Janata Party (BJP) said in a Twitter post he was ready to work with him for the development of the mega-city (Delhi) of more than 15 million people.
Modi also assured him of all support from the Centre for development of the national capital.
"Spoke to @ArvindKejriwal & congratulated him on the win. Assured him Centre's complete support in the development of Delhi," Modi tweeted.
His tweet came as trends showed a massive victory for AAP in Delhi polls in which BJP was decimated.
BJP had emerged as the single largest party in the last Assembly polls in December 2013.
Kejriwal, while thanking Modi for the greetings, said he would like to meet him soon to discuss issues related to Delhi.
He told the Indian PM that he would need the Centre's help, reported several Indian news outlets.
Aam Admi Party (AAP), an upstart anti-establishment party, crushed India's ruling party in an election for the Delhi assembly on Tuesday, smashing an aura of invincibility built around Modi since he swept to power last year.
With the vote of the main national opposition Congress party collapsing, the Aam Aadmi, or Common Man Party, was set to capture nine-tenths of the seats in Delhi, in what Modi's critics said was a warning against the partisan politics of Hindu hardliners in his fold.
Winning power in India's states is critical to control of the upper house of parliament, where Modi's party lacks a majority and has been thwarted in its effort to pass reforms, including wider opening of the insurance sector.
Delhi is a small state, but high profile, and such a comprehensive defeat in the capital is a blow to the BJP's ambitions to capture India's second most populous state, Bihar, in an election later this year.
Congress, the BJP's main nationwide challenger, failed to win a single seat, underlining how far the Gandhi dynasty has fallen.
The BJP, seen as a party of traders and big business, had slumped to 4 seats, its worst showing ever, with its chief minister candidate and former cop Kiran Bedi struggling to win her own seat.
