There is the well repeated incident about what happened when Natwar Singh was Deputy High Commissioner in London in 1975. He tried to get fresh with an English maid ( in India we would call it molesting with the intention of outraging the modesty) and it led to his being punctured by a kitchen knife. The Indian government and Chandraswamy had to pull all stops to hush up the incident.
Later on when Natwar was MOS in the Rajiv Gandhi government he said something offensive about how the then former External Affairs Minister, AB Vajpayee, spent his evenings in London. To which Vajpayee rose to say that, what he did in his private hours was his business and what Natwar might have to say is mere hearsay. But then will be forced to tell the house what Natwar Singh was doing in London, and that it was matter of record and added to good measure that he had seen the file. Natwar fell silent and skulked off.
And this is not hearsay. Atalji himself narrated this incident to me.
