Senior Congress leader Mallikarjun Kharge is likely to replace Ghulam Nabi Azad as the leader of opposition in the Rajya Sabha and the party has written to the chairman of the Upper House of Parliament in this regard, sources said.
The Congress has written to Rajya Sabha Chairman M Venkaiah Naidu for appointing Kharge to the post of leader of opposition after Azad's retirement, they added.
The post will fall vacant after Azad's tenure as a Rajya Sabha member ends on February 15. Azad is a member of the Upper House from Jammu and Kashmir, which does not have an Assembly currently after it was made a Union Territory with the abrogation of Article 370 of the Constitution.
