New Delhi, Dec 30 (IANS): Congress Delhi chief Arvinder Singh Lovely Monday asked BJP leader Nitin Gadkari to name the businessman who, according to the BJP ex-president, brokered a deal between the Congress and the AAP for government formation in Delhi.

"When you make an allegation, then the onus is on you to prove whether the allegation is right or wrong... some businessman had told him (Gadkari) this, then he should name that businessman," Lovely told reporters here.

Gadkari, who headed the Bharatiya Janata Party (BJP) election campaign in Delhi, recently alleged that the Aam Aadmi Party and the Congress struck a deal, brokered by a businessman, to prevent his party's government in Delhi.

This deal, the former BJP president added, was also aimed at derailing the appeal of BJP's prime ministerial candidate Narendra Modi, and the information was conveyed to him by a person who knew about a supposed meeting held at a five-star hotel between representatives of the AAP and the Congress.

The AAP has already asked Gadkari to come out with proof to back his allegation.
