The members of BJP and AAP are "illegitimate sons," Kishan said, while addressing a public rally at Kanjhwala area here today.
The Congress leader had successfully contested the previous Delhi Assembly elections.
Union Minister Sadhvi Niranjan Jyoti had also come under attack from the Opposition parties after she had used an expletive during a public rally in Dwarka earlier this month.
"Aapko tay karna hai ki Dilli mein sarkar Ramzadon ki banegi ya har**zadon ki." "People of Delhi have to decide if they want a Government of Ramzaadon (followers of Ram) or har**zadon (a Government of those who are illegitimate)."
Defending her remarks, the BJP leader later said, "What else do you call people, who loot the nation and its people? I did not take name of any particular individual, community or party. I was talking about separatist parties and leaders who think of dividing the country and who do not consider themselves to be a part of India."
47-year-old Sadhvi Niranjan Jyoti, who was in the eye of storm over her controversial remarks on Tuesday, Dec 2 apologised for using an expletive publicly, during an election rally in Delhi. She is a first-time MP from Fatehpur, Uttar Pradesh. She was inducted in the Modi government as a junior minister for food processing on November 10, 2014.
