London: Now the world knows Prince Harry is in Afghanistan, the question on many lips is whether it was right for the media to keep quiet about it for so long.

Journalists are accustomed to embargoes - almost every day newspapers, newswires, radio and TV stations agree with governments, central banks and companies to release information only at a specific time to make it available to all at once.

In the case of Prince Harry's frontline role in Afghanistan, the embargo just went on for a lot longer than normal - in the end, for a surprisingly enduring 10 weeks.

In a series of meetings at the Ministry of Defence late last year, British media and selected international outlets agreed not to report Harry's deployment in exchange for getting regular pictures, video and text of his day-to-day activities once the planned four-month assignment was completed.

There was a reluctance to sign up to such a deal, and an expectation among many that the "understanding", as it was called, would inevitably, rapidly be broken.
