Natwar Singh tried his luck with BSP after resigning from Congress but the experiment failed miserably as Behenji suspended both Natwar and his son very soon for indulging in anti-party activities.
Natwar's son, Jagat Singh, joined BJP and is presently an MLA in Rajasthan. If Congress general secretary Digvijay Singh is to be believed then Natwar Singh is trying to use his book to create a platform for his son jagat Singh.
Whatever may be the reason, Natwar Singh's scathing attack on Sonia Gandhi and her family through his book can't be ignored factually as it's an account of a person who was privy to whatever was happening in the family and governments.
But what can't be overlooked is the fact that Natwar Singh has made all these revelations only after he was made to quit from the party under embarrassing circumstances. It could very well be the uttering of a man who was considered a family sycophant and who could not tolerate his insult by his masters.
