Copenhagen: Prince Henrik of Denmark has been married to the country's queen for 50 years, and he has been carrying a grudge the whole time. Now, in an act of protest, he says he no longer wishes to be buried by her side, the Royal Danish House announced Thursday.

Behind the decision lies decades of frustration over what he sees as unequal treatment.

Henrik, now 83, married Queen Margrethe II in 1967, and was later bestowed with the title of the queen's prince consort. But what he really wanted was to be king - or in this case "king consort."

"It is no secret that the prince for many years has been unhappy with his role and the title he has been awarded in the Danish monarchy," the Royal Danish House's director of communications, Lene Balleby, told the tabloid newspaper BT. "This discontent has grown more and more in recent years."
