UPA chairperson and Congress leader Sonia Gandhi who was in Rae Bareli to file her nomination, was accompanied by son and party president Rahul Gandhi, who hit out at PM Narendra Modi on the Rafale deal. "(Prime Minister)Narendra Modi is not invincible and in last 5 years has done nothing for the country. I'm perfectly happy for Narendra Modi to take any action against me, he's in charge right now. But he should explain how the Rafale project assigned to Anil Ambani? Why was he given Rs. 30,000 crores? "Ready for an open debate on corruption with Narendra Modi and I guarantee, the day he has a debate, he won't be able to face the country," Mr Gandhi added.
