Accusing Modi of indulging in 'low level' politics, Priyanka said that people of Amethi will never forgive him.
In a statement, she said, "Inhone Amethi ki dharti pe mere shaheed pitaa ka apmaan kiya hai, Amethi ki janta is harkat ko kabhi maaf nahi karegi. Inki neech rajniti ka jawaab mere booth ke karyakartaa denge...Amethi ke ek ek booth se jawaab aayega..."(They have insulted my martyred father on the soil of Amethi. People of Amethi will never forgive them for this act. Workers in Amethi will reply to their low-level politics. There will be reply from each of the booths).
In a Doordarshan interview, allegedly, Modi had said that Priyanka is like his 'daughter', to which Ms Vadra replied that "I am Rajiv Gandhi's daughter".
Later, in a election rally in Amethi,Modi accused Congress of practicing politics of 'arrogance' and said Rajiv Gandhi, when he was Congress General Secretary, had once publicly 'abused' and 'humiliated' the then Andhra Pradesh Chief Minister T Anjaiah at airport.
Earlier in the day, Modi slammed Priyanka Gandhi's alleged remark on Smriti Irani and said this was a reflection of "arrogance" and asserted that she was his "younger sister" and "representative" who knows much more about Amethi than the entire Gandhi family.
On Sunday when Priyanka was asked about the attacks against Congress by BJP candidate Smriti Irani, she asked, "Who"?
"One of their (Congress) leaders even asked who is Smriti Irani? In democracy the royals do not have the right to ask such questions. This is nothing, but arrogance. When arrogance grows, people tend to lose their sense and they ask such questions", said Modi.
He went on to add, "I want to tell who is Smriti Irani. She is my younger sister and she will take care of your welfare and development."
