Congress President Sonia Gandhi, who has been spearheading the UPA's ambitious Food Security Bill, left the Lok Sabha while the voting was underway tonight on various amendments moved by the Opposition.
Gandhi was seen leaving Parliament at 8.15, being helped by Union minister Kumari Selja. Her son and Congress Vice President Rahul Gandhi also accompanied her.
She had viral fever since last night and doctors examined her at her home, sources said.
Earlier in the day, Gandhi led the party in the debate on the landmark bill describing it as a measure to wipe out hunger from the country.
