Conflict of interest: Oppn wants PC to quit New Delhi: The Rajya Sabha had to be adjourned till noon on Thursday after ruckus over a CNN-IBN report that showed conflict of interest by Home Minister P Chidambaram. The BJP demanded Chidambaram's resignation. "Chidambaram misused his powers as the Home Minister, instructed Delhi government and the Delhi Police to withdraw charges. We think it is a big case of conflict of interest. Chidambambaram has no moral authority to remain the Home Minister, he should resign," Rajya Sabha MP Chandan Mitra said. Meanwhile, the Home Ministry has backed Chidambaram on conflict of interest. Home Secretary RK Singh said, "The Home Minister had no role in this. He only said go by the Law Ministry's opinion. No senior advocate ever remembers who he advised a year ago." CNN-IBN had accessed papers which show that the Home Ministry withdrew charges against a hotelier. Chidambaram had represented the hotelier as a lawyer between 1999-2003. The controversy concerns the Metropolitan Hotel in the capital and its owners. The Home Minister, then a practising lawyer was fighting their case. A series of letters and documentary evidence have revealed how Chidambaram, after taking over as Home Minister, continued to take regular interest in the case. He even asked the Delhi Police for investigation updates and Law Ministry for opinion The BJP is saying there is a clear conflict of interest in the Home Ministry moving for withdrawal of charges after Chidambaram took over. Since 1999, the owners of five star Metropolitan Hotel, SP Gupta and his company Sunair Hotels, have been involved in a series of bitter legal disputes with VLS Finance Ltd, a company which claims to have funded the project. P Chidambaram, then an opposition MP, represented Sunair Hotels in the High Court for one the disputes. Even as the civil suits were being heard in courts, VLS Finance filed three FIRs in various Delhi Police stations against the owners of Metropolitan Hotel for defrauding them. Things took an interesting turn when Chidambaram became the Home Minister after the 26/11 Mumbai attacks. Documents available with CNN-IBN show that the Home Ministry started actively working on representations sent by Sunair, asking for withdrawal of the criminal cases. Several letters were then sent by the ministry to Delhi Police asking for clarifications and status reports so that a decision on withdrawing cases against Sunair Hotels could be taken. The ministry even wrote to the Delhi police commissioner asking for the status of investigation for appraising the Union Home Minister.
