In a no-holds-barred attack at Andhra Pradesh Chief Minister Chandrababu Naidu, Prime Minister Narendra Modi on Sunday said the TDP chief is "a senior in switching sides and stabbing his father-in-law in the back" among other things.

His remarks were a comeback at Naidu for his statement that he addressed the Modi as "sir" to satisfy his ego even though the Prime Minister was junior to him in politics.

Addressing a rally in Andhra's Guntur district, Modi said, "He (Naidu) keeps reminding me he is my senior. But you are a senior in changing parties. You are a senior in making alliances with new parties. You are senior in backstabbing your father-in-law (TDP founder NT Rama Rao). You are senior losing every other election."

This is Modi's first visit to Andhra Pradesh, a year after the ruling Telugu Desam Party walked out of the BJP-led NDA.

"He (Naidu) had promised the sunrise of Andhra Pradesh but he seems more interested in his son's rise. He had promised to launch new schemes for the poor of the state but he has just put his sticker on Modi's schemes," the Prime Minister said.

Late last month, Naidu had attacked Modi saying he addressed the Prime Minister as "sir" to satisfy his.

"When I met then US President Bill Clinton, I addressed him as Mr Clinton, not as 'sir'. Modi is my junior in politics. But when he came (to power), I addressed him as sir 10 times. I did this for the sake of the state and to satisfy his ego in the hope that he will do justice to the state," the Telugu Desam Party (TDP) chief had said.

The Chandrababu Naidu-led party quit the BJP-led alliance protesting the "injustice" done to the state post-bifurcation.

On Sunday, TDP workers staged protests against the Prime Minister as he arrived Sunday on his first visit to the state after the ruling TDP severed ties with the NDA.

At Vijayawada and Guntur, TDP workers donned black shirts and took out rallies demanding that "Modi go back".

Giving the protocol a go-by, none of the state ministers turned up at Vijayawada airport to formally receive the Prime Minister, who is on an official-cum-political visit.
