‘‘It is a tradition that the permanent members of the UNSC or countries aspiring to be its permanent members do not field candidates for the post of the UN Secretary General,’’ he said. Responding to a correspondent’s question on the nomination of Tharoor for top UN post, he said the UN diplomat was welcome to join the race. ‘‘The more the merrier,’’ he said. At the same time he hinted that Pakistan would also field its own candidate for the post of UN Secretary General. The matter has been under consideration for quite some time now, he said, adding that the decision is yet to be taken by Islamabad.
