Why did Kuldip Nayar apologise to Shekhar Gupta at his book launch? The book in question makes uncomplimentary references to Gupta at more than once place and is artless enough to also say that Gupta dropped Nayar's Indian Express column, thereby suggesting one reason for the pique. Because some of the comments can be construed as libelous, both Nayar and publisher Pramod Kapoor of Roli Books were inviting trouble. Gupta hit back at Nayar at an Editors Guild seminar where Nayar was seated upfront. He referred to journalists who accept Rajya Sabha nominations as well as stints as High Commissioner. Both of which Nayar has done.
