The Congress on Tuesday appointed senior leader N.V. Raghuveera Reddy as president of its Seemandhra unit.
Congress president Sonia Gandhi telephoned him to congratulate on his appointment to the top post, party sources said.
The party has still not named the chief of its Telangana unit.
Raghuveera Reddy, a former state minister, told reporters in Anantapur that he is taking up the responsibility at a difficult time. He vowed to strengthen the party with the support of all leaders and workers of the party.
