Why didn't you debate with me on Rafale? Rahul questions PM Modi

Congress President Rahul Gandhi: Now that the Prime Minister is doing a live press conference, I want to ask him 'why didn't you debate with me on Rafale? I had challenged you for a debate, tell the press why didn't you debate?'
INC Chief later tweeted "Congratulations Modi Ji. Excellent Press Conference! Showing up is half the battle. Next time Mr Shah may even allow you to answer a couple of questions. Well done!"
