Rewa, Sep 17 (ANI): Narendra Modi is a challenge for BJP stalwart Lal Krishna Advani and the saffron outfit, and not for the ruling party at the Centre. The Congress leader's remark came just days after the infighting within the BJP following Modi's anointment as the prime ministerial candidate came to the fore with Advani appearing to be a stumbling block in the way of the Gujarat Chief Minister's elevation. Advani, however, yesterday broke his silence and appreciated Modi's Gujarat development model at a rally in Chhattisgarh.
