Well, then it might have escaped the "Danish papers" - which do you mean? - that Frederik was Regent on 62 days in 2007. It might also have escaped their attention how - apart from his trip to Mozambique - relatively empty Joachim's calendar was since the announcement of his engagement. 30 occasions where he stepped in for the queen, I wonder which were those occasions?
Get me right, I don't criticize Joachim. I think he has been treated quite unfairly by the media in the past. But I think you are over-praising his workload and at the same time belittling the one of his brother, for reasons whatsoever. I am watching the calendar of the DRF and it is quite clear that - after the Queen - Mary and Frederik are the ones with the most official events nowadays. You make it sound as if Joachim works more than his brother, when he actually does not.
I can't speak for all but I personally get sore when facts are distorted. IMO in most cases you are distorting facts (see e.g. your comment about the poll in BB in another thread or your claim to be the first to report positively about Joachim - no, others have done that before you).
I would guess it was because it was a birthday, not a charity event.
And why wasn't the birthday of Willem Alexander turned into a charity event? And why wasn't the birthday of the king of Sweden turned into a charity event? And why wasn't the birthday of the king and queen of Norway turned into a charity event? ...
Ekstra Bladet, Jyllands-Posten, Politiken were the ones I saw the story in. Of course Prince Joachim's royal calendar is not as full as CP Frederik's. He has a full time job running Schackenborg! All his royal duties come on top of his duties at Schackenborg. The birthday party was in MY opinion a perfect opportunity for CP Frederik to show us Danes how he wants to modernize the monarchy. All this royal over-the-top.partying is oldfashioned and not in tune with the times. Those of us, who want to take the monarchy forward, would like to see a Crown Prince and Crown Princesses being far more aware of the fact, that they have to lead by example! Others might prefer to keep on insisting that the emperor is wearing clothes, but I am not one of them!
