The Aam Aadmi Party on Monday expressed displeasure at the latest campaign advertisement published by the Bharatiya Janata Party, which described party chief Arvind Kejriwal as a person of anarchist 'gotra' (sub-caste). AAP leader Ashutosh came down heavily on the BJP, saying people will teach the saffron party a lesson in the upcoming Delhi Assembly elections.

"BJP stooped another low. Now it has attacked Kejriwal's GOTRA in today's advertisement. People belonging to his GOTRA will teach BJP Lesson (sic)," he wrote on Twitter.

In the third cartoon of the series, the BJP took potshots at Kejriwal's dharna just before the Republic Day in 2014, and his demanding an invitation for the Republic Day parade this year. In the small text below the cartoon, the BJP called Kejriwal of upadravi gotra (anarchist gotra).

On Sunday, the BJP released a campaign advertisement against Kejriwal, taking a quip on a pre-poll promise made by him during the last Delhi Assembly elections that he wouldn't accept government bungalow if he came to power. The BJP also appealed to the voters not to vote for the AAP.

Kejriwal had accepted a government bungalow after becoming the chief minister.

BJP's anti-AAP newspaper ad on Friday showed a caricature of Arvind Kejriwal taking a vow on the heads of two children, as a woman with a Congress cap watches coyly. In the background is a caricature of Anna Hazare, put inside a frame and draped with a garland (as done to pay respects to the departed).

The AAP was furious at the crass ad, with Kerjiwal even saying that the BJP "has killed Anna in its ad today".

"Nathuram Godse killed Gandhiji on this day in 1948. BJP has killed Anna in its ad today. Shudn't BJP apologise? To all AAP volunteers n supporters. Evil forces will try to divert ur attention. But pl stay focused on positive agenda for Delhi," the AAP leader and party's CM candidate had said on Twitter.

"AAP is forming govt in delhi. Get ready to serve Delhi and to make it safe for women. I will always pray for well being and good health of Annaji. As we remember Gandhi ji on the day of his martyrdom, we must reaffirm our pledge to his beliefs, his idea of a diverse and harmonious India," he tweeted.

Earlier, the BJP had targeted the AAP for labeling its chief ministerial candidate Kiran Bedi as an "opportunist" and projecting Kejriwal as "honest" in its poll ads.
