Sonia Gandhi had not campaigned for the party during elections in the recent past due to health reasons.
It will be after a long time that Gandhi will participate in the party’s public event where a large number of Congress workers are participating. The Bharat Jodo Yatra entered the 26th day of its almost five month journey from Kanyakumari to Kashmir.
Former Congress president Rahul Gandhi will undertake the entire 3,570 km Yatra.
