"I was in service for the past 35 years. I wanted to do something new and out of the government... that is the reason I have applied for voluntary retirement," Sinha, 55, told IANS over phone.
He said "the decision is personal and I have no purported difference with the government".
Sinha, who also holds charge of the power portfolio, earlier worked with the UN mission in Afghanistan and with the World Bank.
