A political row erupted on Friday after a video clip purportedly of AAP minister Rajendra Pal Gautam at a "religious conversion" event went viral in which hundreds can be heard taking an oath denouncing Hindu deities, with the BJP launching an attack on Chief Minister Arvind Kejriwal and asking him to sack his cabinet colleague.

Gautam, in a programme at Central Delhi's Karol Bagh on Dussehra, showed "disrespect" towards Hindu deities in the presence of thousands of people, Delhi BJP president Adesh Gupta charged during a press conference.

"This is not an isolated incident, it is in the character of the AAP to insult and disrespect Hindu gods and goddesses. We demand that Kejriwal should immediately expel Gautam from his cabinet," Gupta said.

Gupta also led a party delegation to file a complaint with the police here in the matter.

At a press conference, BJP national spokesperson Gaurav Bhatia accused the AAP of hurting the sentiments of Hindus and alleged that "Gautam's comments highlight the hate" the party has for the community".

Bhatia claimed that the minister's alleged comments were made at the behest of Chief Minister Arvind Kejriwal.

Sources in the Aam Aadmi Party claimed that the chief minister was "extremely displeased" with Gautam.

However, an immediate response was not available either from the chief minister or the Delhi government.

Gautam is the social welfare minister in the Arvind Kejriwal government.

During the programme, around 10,000 people reportedly took vows to convert to Buddhism to follow Lord Buddha's teachings and give up worship of Hindu deities.

On October 5, Gautam himself had also tweeted the pictures of the event, saying more than 10,000 people pledged to join Buddhism and work for making India free from casteism and untouchability.

BJP MP Manoj Tiwari also demanded Gautam's sacking, claiming his action could lead to animosity between Hindu and Buddhist communities.

Hitting out at Gautam, West Delhi MP Parvesh Verma accused him of indulging in "mass religious conversion".

"Every day news of conversions comes from AAP-ruled Punjab. Similarly, Kejriwal's minister Rajendra Pal is now conducting a mass conversion of people in Delhi," Verma said in a tweet.

Bhatia said the comments were made due to "vote bank" politics in light of the coming elections, he said.

"How low you will stoop for votes, Kejriwal," he asked. Bhatia said every Hindu has faith in their gods and claimed that the minister's comments are a blow to national integrity.
