New Delhi: Bihar Chief Minister Nitish Kumar on Wednesday upped the ante in the race for the BJP-led NDA's prime ministerial candidate by directly targeting Gujarat Chief Minister Narendra Modi. Nitish claimed that Modi's 'mishandling' of the 2002 Gujarat riots led to him (Modi) almost being sacked by the then prime minister Atal Bihari Vajpayee as he had not followed 'Raj Dharma'.
