Telangana Rashtra Samithi (TRS) leader Kalvakuntla Chandrashekar Rao (KCR) met Congress Vice President Rahul Gandhi on Monday.
Congress leader Digvijay Singh and Priyanka Gandhi will also be present in the meeting.
KCR had met Congress President Sonia Gandhi yesterday to express his gratitude for passing the Telangana Bill.
The meeting led to speculations over the possibility of KCR aligning with the Congress.
"I have met Sonia Gandhi to express my gratitude for the passage of the Telangana bill. All our family members have come to meet her," said Rao.
"She has assured me that she is going to address all our concerns and discuss it with the PM. Digvijay Singh will be in touch with me in the meantime," he said.
"She said she would call me back for another meeting. I am here in Delhi for few more days as I am planning to meet the Prime Minister Manmohan Singh as well," he added.
