After an hour long meeting with Gandhi, Rao told mediapersons that Sonia told him that she will consult Prime Minister Manmohan Singh, the All India Congress Committee in-charge of AP and other Congress leaders before any decision is taken.
Sonia's political secretary Ahmed Patel was also present. Rao, who was called to Delhi by the party high command for discussions, said Sonia also inquired about Rajasekhara Reddy's family and wanted to know whether they have overcome the shock.
Before meeting the Congress chief, Rao said, "Everything is left to the high command. Whatever madam Sonia Gandhi decides."
K Rosiah is currently the state's interim chief minister. Rao is believed to have piped down and put the open campaign on hold following high command's whip.
