The serious allegations levelled on October 5, 2012, by Mr Arvind Kejriwal and Mr Prashant Bhushan against Mr Robert Vadra, the husband of Ms Priyanka Gandhi and son-in-law of Mrs Sonia Gandhi, the Congress(I) President, cannot and should not be dismissed as politically motivated or opportunistic. They may ultimately turn out to be so, but till they are proved to be so, they have to be treated seriously.
