Sunil Mittal of Airtel has been extensively reported in newspapers from Barcelona, commenting on the imminent spectrum auction. The Economic Times had both a front-page story and a half-page Q&A with him inside; Rediff, PTI, and the Times of India also had stories. Only the Hindu Business Line revealed how the correspondents got there: "at the invitation of Telenor". Telenor was to host a media seminar at its hospitality stand. No disclosures at the bottom of the story by the others.
