Chairman of the Rajya Sabha Ethics Committee, Dr. Karan Singh, is said to have taken seriously the manner in which former MP Vijay Mallya brought disrepute to the Rajya Sabha. To ensure that such a scandal does not recur, the committee has sent out a questionnaire to all Rajya Sabha members reminding them of the Assets and Liabilities Rules, which state that MPs are obliged to notify if there is any change in their assets and liabilities furnished by them by June 30 every year. An accompanying form seeks details of loans raised from banks and financial institutions. On May 3, the Ethics Committee recommended the expulsion of Mallya, rejecting his defence of loan default of over Rs 9,400 crore. Hours after the committee's report was submitted, Mallya sent a fresh letter of resignation to Rajya Sabha Chairman Hamid Ansari, which was accepted, before the committee's recommendation could be taken up for action.
