This is now all over the Indian press. Times of India has a nice article. Some excerpts:
But apart from Tharoor, Dhanapala, one of the strongest candidates for the top job, is the only other with a long stint in the UN.
Tharoor's advantage is that though he is identified with India, he is not part of the Indian government, not even the foreign service. However, he is also known to be one of Kofi Annan's favourites and this could go against him.
But the really interesting bit is the part about what Shashi has to do about reform:
In fact, to promote his candidature, Tharoor will now be required to come up with a script for UN reform that marks a qualitative improvement upon Annan's, and, more acceptable to countries like US which will have a decisive say in determining who gets the slot at stake.
Thus far, he has stuck to the spirit of the reform exercise, saying: "The UN needs reform not because it has failed but because it has accomplished enough over the years to be worth investing in."
