BJP president Rajnath Singh said the influence of the Bahujan Samaj Party has been confined to Uttar Pradesh and there was no possibility of its chief Mayawati becoming the Prime Minister. “Everyone has a right to dream but such dreams should be based on reality. Mayawati is harbouring a totally unrealistic ambition of becoming the Prime Minister,” the BJP chief said.Regarding the forthcoming Assembly polls, he said the BJP will win in Madhya Pradesh, Rajasthan, Chhattisgarh and Delhi. He ruled out the possibility of a Third Front at the Centre saying its likely constituents had started joining the BJP-led NDA.Singh, however, refused to comment on reports of Ajit Singh-led Rashtriya Lok Dal joining the NDA. He also declined comments on reports about VHP leader Pravin Togadia’s links with Abhinav Bharat, a right-wing group suspected to be involved in the Malegaon blasts.
