Finance Minister Pranab Mukherjee has avoided direct comment on a note from his ministry to the Prime Minister's Office (PMO) saying airwaves for telecom could have been auctioned in 2008 if his cabinet colleague P. Chidambaram had wanted. Speaking at a high-profile event organised by the Asia Society here Wednesday evening, Mukherjee acknowledged such a note had indeed been written by his office but declined further comment on the matter, saying it was sub judice reported by the news agencies.
