Singh was a senior Minister in the Atal Bihari Vajpayee-led NDA government in which he held important portfolios of External Affairs, Defence and Finance.
Meanwhile, Manvendra Singh, Jaswant Singh's son, who is currently an MLA in the Vasundhara Raje-led government in Rajasthan, has also indicated that he might follow in his father's footsteps.
When contacted, Manvendra told PTI that he was “extremely stressed out” and was resting.
Rejecting reports that he has written to the BJP about the current situation, he said, “I have not written to the party and I have informed the party that I am stressed out and need some rest.”
