The saffron party sought an apology from the Congress.
Singh's crass comments demonstrate the degeneration of a party that prides itself on a great legacy. These comments amount to insulting 130 crore people of India whose mandate is vested in the prime minister, BJP spokesperson G V L Narasimha Rao said.
"The Congress will have to publicly apologise for the filthy abuse of its front-ranking leaders who in the wake of repeated electoral drubbings have degenerated into abusive trolls on the social media," he said.
"I have said it is not mine. I have disowned it. I have not used those words," he clarified, adding that "my tweet does not endorse this".
