Prime Minister Narendra Modi on his first visit to Andhra Pradesh, after the Telugu Desam Party (TDP) broke out of an alliance with the BJP last year, launched a string of attacks on Chief Minister and political rival Chandrababu Naidu. "Why does he (Chandrababu Naidu) often claim that he is senior to me? Yes, he is senior to me in switching sides, forming new alliances and "backstabbing" his seniors - just the way he deceived his father-in-law (NT Rama Rao)," said PM Modi, adding that Mr Naidu was using public money to make several visits to Delhi for his meetings with so called alliance partners. Mr Naidu is losing popularity in his state, alleged PM Modi.
