A large number of Congress supporters gathered to catch a glimpse of both Ms Vadra and Mr Gandhi who is pitted against BJP's Smriti Irani and AAP's Kumar Vishwas in the May 7 Lok Sabha battle for Amethi seat.
The vehicle carrying them moved slowly as the huge crowd waved Congress flags and shouted slogans eulogising Mr Gandhi. Some enthusiastic supporters showered rose petals at them.
The 2km roadshow by the Gandhi scion comes on the eve of BJP's prime ministerial candidate Narendra Modi's campaign in Amethi in support of Smriti Irani.
Ms Vadra who had campaigned for Sonia Gandhi in Rae Bareli which went on polls on April 30, has been aggressively seeking support for her brother.
