The Bharatiya Janata Party on Monday refused to defend its leader Sher Singh Dagar who appears in a sting video released by the Aam Aadmi Party in which Dagar is seen purportedly offering Rs 4 crore to AAP MLA from Sangam Vihar, Dinesh Mohania.

Sources said a section of BJP leaders was strongly opposed to the idea of defending Dagar and said providing the party platform to the leader will be an embarassment. The BJP cancelled a press conference it had called at 2 pm on Monday.

Meanwhile, Dagar claimed that Mohania approached him to join the BJP. "He came to me and said that he wanted to join BJP. If someone visits me, how can I not attend to the person?" he said.

"If BJP wants to expel me, then they can. I have not done anything wrong," he said.

Meanwhile, RP Singh, BJP MLA from Rajendra Nagar, has demanded the suspension of Sher Singh Dagar.

Rubbishing Dagar's claim, Mohania said, "I was directly approached and then I informed the party about it. Talks were going on before also and now all videos are available."

"If BJP expels Dagar, will they also expel all those who appear in future stings?" AAP chief Arvind Kejriwal said.

"We will submit the sting's raw footage to the Supreme Court tomorrow. We will also lodge FIRs and approach the Election Commission of India," Kejriwal said.

Congress demands fresh polls in Delhi

Congress leader Ajay Maken on Monday demanded that the "senior" Dagar is purported to be talking to in the sting video should be identified. "We want to know who that person in the BJP High Command is," Maken said, adding, "BJP's real face has been exposed."

Demanding the dissolution of the Delhi Assembly, Congress asked the Supreme Court to take cognizance of the sting video.

The AAP-BJP spat over horse-trading

Last week, Delhi Lt Governor Najeeb Jung, in his report to the President of India, sought permission to call the single largest party, the BJP, to take a shot at power even though it is well short of majority in the Assembly.

The AAP on Saturday said Jung's offer was an "open invitation for horse-trading" and would amount to the "murder of democracy".

"It is clear that in the absence of support of the Congress party or AAP, the BJP is not in a position to win a confidence vote, except by engineering defections," Kejriwal's letter to President Pranab Mukherjee said.

Home Minister Rajnath Singh had dismissed Kejriwal's accusation and said his party will not indulge in horse-trading in order to form the government in Delhi, which is under the President's Rule since February 17 following the resignation of the 49-day AAP government.

Even after three of its MLAs were elected to the Lok Sabha in the last general elections, the BJP remains the single largest party in Delhi Assembly with 29 MLAs. The AAP has 27 while the Congress has eight in the 70-member House.
