NEW DELHI: A day after BJP parliamentary board decided to shield party president Amit Shah from taking responsibility for its debacle in the Bihar assembly elections, a senior party leader from the state has put the blame squarely on the party’s central leadership.Launching a blistering attack on the BJP leadership for the Bihar defeat, Bhola Singh Lok Sabha MP representing Begusarai, alleged that under Shah the party contested the elections like a "giroh" (gang) and that Prime Minister Narendra Modi didn’t behave like a PM during his campaigns."Prime minister stooped to the level of Lalu Prasad in the election campaign, violating all propriety of his position," Singh told ET over phone from Bakhtiyarpur on his way to Patna. He also alleged that just a handful of people were involved in the BJP’s campaign under Shah. "I think that we didn’t contest elections like a party organisation but as a 'giroh'," Singh told ET."Char logon ka giroh chunao lada. Wahi log poster per the, parchon mein the, aur helicopters per the." (A gang of four contested the elections. They were on the posters, pamphlets and in helicopters.)Singh said old committed workers of the party were made to cool their heels in the "shadows" of the ‘giroh’ that included leader of opposition in state assembly Nand Kishore Yadav, Bihar BJP legislature party leader Sushil Modi and state unit chief Mangal Pandey besides Shah."A committed worker like me was ignored during elections," Bhola Singh said.He didn’t spare the prime minister either. "In Bihar, PM was not behaving like PM but like Lalu Prasad," Singh alleged. "PM fell into Lalu’s trap. The issue of Bihar’s backwardness was left behind and PM started talking about ‘jantar-mantar’ (exorcism) while on another stage he was sharing dais with a liquor contractor. It didn’t do justice to the PM’s image," he added."He didn’t remain as PM. While he should have been talking about social harmony and spreading awareness about the need for development, he started talking that he was son of a ‘teli’. The position of PM has some dignity, but in Bihar the PM started speaking the language of Lalu Prasad," Singh alleged.Hitting out at Amit Shah’s unilateral style of working, he also called for an impartial review of Amit Shah’s work before the party’s presidential elections in January. "Our national president was preaching like Krishna from Gita. President is considered consensus builder, ensuring two banks of river remain in tandem. He didn’t do so," Bhola Singh alleged.He said such a thing never happened in BJP earlier. "I have seen Vajpayee and Advani working," he said. Shah just wants everyone to tow his line, Bhola Singh alleged. " Unhone jo paros diya wahi gao . Jyada sochna nahin , samajhna nahin ," he said.
