ED opposed Robert Vadra's plea saying he has been given sufficient opportunity to come out with proof.
Robert Vadra on Monday claimed before a Delhi court that ED has been leaking details of his interrogation to the media to "embarrass" and "humiliate" him on account of a "political vendetta", a charge strongly denied by the probe agency.
Special Judge Arvind Kumar, who extended Robert Vadra's interim protection against arrest till March 27 in a money laundering case, was told by the counsel for the brother-in law of Congress President Rahul Gandhi that every question and answer of the interrogation has been leaked to the media with some ulterior motive.
This showed that the Enforcement Directorate's probe was meant to "embarrass" and "humiliate" Robert Vadra on account of a "political vendetta" and the agency was guided by the "lust for custody", said senior advocates AM Singhvi and KTS Tulsi appearing for Robert Vadra.
ED's counsel DP Singh countered the submission vehemently saying, "They talked about agency's ''lust for custody''. It is their ''lust for money'' which has led to our ''lust for custody''.
At the outset of the hearing on the anticipatory bail plea of Robert Vadra, KTS Tulsi claimed that even the raid conducted on the businessman's house to obtain documents was "illegal" and moreover, Robert Vadra has not misused the liberty granted to him.
The ED case relates to allegations of money laundering in the purchase of a London-based property at 12, Bryanston Square, worth 1.9 million pounds. The property is allegedly owned by Robert Vadra.
The court also extended the interim protection from arrest granted to Manoj Arora, Robert Vadra's close aide and an accused in the case, till the next date of hearing - March 27.
ED opposed Robert Vadra's bail plea saying he has been given sufficient opportunity to come out with some proof against the allegations levelled against him by the agency but so far, he has failed to do so.
It further said that the offence was about the money coming as kickbacks, as direct payments to bank accounts.
It alleged that the case involved payment of Rs 300 crore in a defence deal and USD 10 million received in a petroleum deal.
ED's counsel submitted that he requires more time to conclude his arguments and to present certain details before the court.
The court had on March 19 extended his interim protection from arrest till March 25 after the ED had alleged that he was not cooperating and sought his custodial interrogation.
ED had told the court that there was reasonable apprehension that Robert Vadra being a highly influential person would tamper with the evidence and hamper the investigation.
In his anticipatory bail plea, Robert Vadra has alleged that he was being subjected to "unwarranted, unjustified and malicious criminal prosecution which on the face of it is completely politically motivated and is being carried out for reasons other than those prescribed under law".
The ED had also alleged that Manoj Arora, an employee of Vadra's Skylight Hospitality LLP, was a key person in the case and he was aware of the latter's overseas undeclared assets and was instrumental in arranging funds.
It told the court earlier that it lodged the money laundering case against Manoj Arora after his role came up during the probe of another case by the Income Tax Department under the newly enacted Black Money Act and tax law against absconding arms dealer Sanjay Bhandari.
It alleged that the London-based property was bought by Sanjay Bhandari for GBP 1.9 million and sold in 2010 for the same amount despite incurring additional expenses of approximately GBP 65,900 on its renovation.
"This gives credence to the fact that Sanjay Bhandari was not the actual owner of the property but it was beneficially owned by Robert Vadra who was incurring expenditure on the renovation of this property," the ED had told the court.
ED said it has received information about various new properties in London which allegedly belong to Robert Vadra, including two houses of five and four million pounds each and six other flats.
