The Prime Minister's Office has denied that Jaswant Singh had named the 'mole' in his letter to Prime Minister Manmohan Singh.

"No such name has been given by Jaswant Singh," the prime minister's media adviser Sanjaya Baru told reporters in Delhi.

Baru said since Saturday many sections of the media have been reporting that some name had been given to the prime minister by Jaswant Singh, in an apparent reference to the former external affairs minister's claim in Mumbai on Saturday that he had revealed the name of the 'mole' in P V Narasimha Rao's regime who had leaked nuclear secrets to the US.
