Bihar Chief Minister Nitish Kumar, 65, has always publicly described Lalu Yadav as his "big brother". In their alliance, as well, it is Mr Yadav who makes the larger contribution with his party outperforming that of Mr Kumar's in the last election in 2015. So Mr Kumar owes his seat of power to Mr Yadav. But when Lalu reached a public function today in Patna, he was asked politely to vacate the chair he had occupied with the organisers explaining it was reserved for the Chief Minister.
