Hyderabad, Sep 6 - Y.S. Jaganmohan Reddy, son of late Andhra Pradesh chief minister Y.S. Rajasekhara Reddy, Sunday appealed to his followers to be calm and maintain discipline, and said that Congress president Sonia Gandhi would soon decide on the leadership issue.

He made the appeal hours after his followers disrupted a meeting at party headquarters held to mourn YSR's death, and demanded that the party leadership name Jagan as the new state chief minister. YSR died in a helicopter crash Wednesday.

Jagan's supporters did not allow state Congress president D. Srinivas to speak, forcing him to hastily wind up the meeting in the presence of acting Chief Minister K. Rosaiah.

Jagan, the Kadapa MP, said he was pained at some of his supporters going to the media with their demand to make him YSR's successor.

'We all have a responsibility, as true followers of his legacy, to work towards fulfilling his unfulfilled dream. We cannot afford to lose our heart and become panicky. We have to somehow summon courage and maintain calm and composure, and pay our silent and respectful homage to him,' he said in his four-page statement released by the Congress Legislature Party (CLP).
