Prime Minister-designate Narendra Modi on Sunday assured Tamil Nadu chief minister and AIADMK chief J Jayalalithaa of the Centre's cooperation to the state.
Modi gave this assurance in a telephone conversation, during which he also congratulated Jayalalithaa on her party's stupendous victory in the Lok Sabha elections.
Modi was responding to a letter from Jayalalithaa congratulating him for his party's "magnificent win".
In the letter sent on Friday, Jayalalithaa had said she looked forward to an era of meaningful cooperation between the government of Tamil Nadu and the government of India.
A Tamil Nadu government release said Jayalalithaa wished Modi a successful tenure as Prime Minister of India.
The AIADMK went alone in the general elections this time and bagged 37 of the 39 Lok Sabha seats in Tamil Nadu.
In the heat of polling, Modi and Jayalalithaa had not shied away from attacking each other.
On May 15, a day before the election results were declared, Jayalalithaa had expelled party MLA K Malaisamy for hinting at a possible post-poll alliance between the AIADMK and the BJP-led NDA.
In a terse expulsion order, Jayalalithaa had said Malaisamy was being expelled for "bringing disrepute" to the party by making statements contrary to its policies.
Jayalalithaa had earlier told the media that she would comment on her party's strategy only after the election results were out.
