Sonia claimed that Gujarat has progressed due to the Congress rule, and added that the central government is committed to national security.
Criticising the Modi government for not utilising the central funds, Sonia said, "Congress-led UPA sanctioned more funds to Gujarat than BJP-led NDA government."
Sonia will also be addressing another rally in Mehsana. She is also expected to address a media briefing in Ahmedabad.
During her whirlwind tour of the state earlier, Sonia had sharpened her attack on Modi who is seeking a third consecutive term in office.
She had accused Modi and his BJP-led government of failing to meet the aspirations of the people of the state.
"They (Modi and BJP) have no interest in poor and common people but its only interest is development of its own and a select few people. The development which was promised in a big way is nowhere to be seen in this tribal land...because what they promised were hollow and false," Sonia said.
