Besides Patil, party General Secretary Ghulam Nabi Azad, who is in charge of the state, will also attend the meeting.
"We would like to congratulate the people of Andhra Pradesh for reposing their faith in the Congress, its leader Sonia Gandhi, the party's policies and programmes," Azad told reporters in New Delhi.
Asked who the state's new chief minister would be, he said, "I don't know but we would like that the CM shoud be one among the MLAs."The Congress said it would like its ally, the Telengana Rashtra Samithi, to be part of the new government in Andhra Pradesh and it was for the Left parties to decide whether they would like to be in it.
"We (the Congress and TRS) contested the election together and they would be very much part of the government," Azad said.
