Who's the next Cabinet Secretary?

Now, with Cabinet Secretary Ajit Seth having got another six-month extension, what do the Cabinet Secretary sweepstakes look like? One theory is that the last man standing will be Power Secretary P K Sinha, who is scheduled to retire on June 30, 2015.

The thinking goes thus: that former Prime Minister Manmohan Singh left a trail of destruction when he did deep selection in the case of former National Security Advisor Shivshankar Menon (who superseded 13 people when he was made the Foreign Secretary). This government does not want to take any such chances. So Sinha, who is the seniormost (1977 batch), will still be in service on June 13 when Seth retires. There is a good chance he may become the Cabinet Secretary. Other hopefuls like Saurabh Chandra will retire before him.
