Congress vice-president Rahul Gandhi, who is on the last leg of his campaign in BJP-ruled Gujarat, again credited his pet dog when asked the secret of his recent sharp tweets, which have been drawing a lot of attention on social media. "I said it is Pidi who tweets," Mr Gandhi replied to cheers and whistles at a meeting with social media volunteers in Banaskantha district. Then he added, "The political tweets are mine, but not the routine stuff like birthdays. I suggest few things to my communication team and then we fine tune it".
