She is travelling to Greece on the Royal Yacht is she not, and if she is to have a reception there for the greek president there, it is nothing that can prevent her from decorating the ship with pictures of her sister and brother in law in full regalia
I read that when Spain hosted the first greek statevisit after Sofias brother was kicked out she, who usually only wears smal tiaras for presidentail visit, took out her biggest grandest tiara she only uses for some royal state visits and her highest greek order, and quite snappishly told the President who tried to explain her something that he was speaking to the Queen of
Spain now.
I do not think those vounds are copletely grown in the closest family
But can Margrethe really deny going on a state visit to Greece, if the Danish goverment want a visit she will have to go wont she?
