“We have information that the surgery was successful and her condition is satisfactory,” Dwivedi said. Party, however, did not reveal the country where she has been treated. Party sources said she was in the US.

Dwivedi  said that Mrs Gandhi has formed a four-member team which include general secretary Rahul Gandhi, Defence Minister A.K. Antony, Janardhan Dwedi and Ahmed Patel to look after party matters in her absence.

“Sonia Gandhi has been recently diagnosed with a medical condition that requires surgery. On advice from her doctors, she has travelled abroad and is likely to be away for two to three weeks,” Dwivedi said.

Party leader and worker in different part of the country were conducting prayer meetings for early recovery of their leader.
