Prime Minister Narendra Modi, doubling his push for Bihar votes today, extended the Yuvraj (Crown prince) jibe to two more leaders -- Rahul Gandhi and Akhilesh Yadav -- and cited the BJP's victory over them in neighbouring Uttar Pradesh a few years ago. In Bihar too, two Crown Princes are fighting to save their throne, he said, without naming Rahul Gandhi, who held a series of rallies in the state earlier this week. The other is Tejashwi Yadav, whom he has designated "Jungle Raj ka Yuvraj" earlier this week in the most direct attack so far at the 31-year-old political heir of Lalu Yadav.
