Patna: Tejashwi Prasad Yadav dubbed chief minister Nitish Kumar a bad uncle ( kharab chacha) on Wednesday to applause from his partymen and said the leader was under tremendous pressure in alliance with the BJP.

Leader of Opposition in the Assembly Tejashwi said: "The Shiv Sena has decided to contest (Assembly and Lok Sabha) elections separately and not in alliance with the BJP. I can understand the pain of Shiv Sena. It did not like to be pressed down by others but there is our Palturam (turncoat - a name RJD chief Lalu Prasad gave Nitish after the break-up of the Grand Alliance government) who likes to be pressed down to remain on a post. I can understand Nitishji's pain. He is my uncle so it is obvious that I will care for him even though he has become a bad uncle."

He was speaking at a function marking former chief minister Karpoori Thakur's birth anniversary at the RJD office. As he called Nitish a " kharab chacha", supporters gave a huge round of applause.

Tejashwi too laughed. "I know that he is under tremendous pressure in alliance with the BJP. He is so tense, all the time he thinks about how he will not get a single of the 40 Lok Sabha seats with the BJP. Day and night he thinks about how to get more seats in the Assembly."

Sitting in father Lalu Prasad's chair the day the RJD chief was convicted in another fodder scam case, Tejashwi said the BJP did not have a big heart like his father who accepted Nitish as the chief minister in spite of the RJD getting more seats than the JDU in the 2015 elections. The RJD had won 80 seats to JDU's 71.
