The third child of the last king of Greece has announced he is getting divorced after 14 years of marriage.

Nikolaos Glyksburg, third child of Constantine II, and his wife Tatiana announced their separation on Friday.

“Prince Nikolaos and Princess Tatiana after 14 years of living together, have decided to dissolve their marriage,” a statement on the former royal family’s website read.

The statement expressed “the difficulty of this decision, the deep appreciation and respect they have for each other, but also the love with which they have walked all these years.”

The couple met during a ski holiday in Switzerland in 2003 and announced their engagement six years later.

Their wedding on the Greek island of Spetses in the summer of 2010 was one of the society events of the year and was attended by guests including royalty from Denmark, the Netherlands and Spain.

Since the wedding the couple have lived together in Athens. They have not had children together.

Tatiana dedicated much of her time to philanthropic causes while Nikolaos has a passion for photography.

The couple were believed to be happily married for much of their union but rumours had been swirling in recent months of an estrangement between the pair, according to the Greek media.

The couple were last seen together in public in February when they attended a memorial at Windsor to mark the first anniversary of the death of Mr Glyksburg’s father, Constantine II.

Nikolaos was born in 1969 in Rome after his father, Constantine II, had fled Greece during a period of military dictatorship in his home country.

In the 1970s, the Greek people voted in two referendums to replace their monarchy with a republic.

Nikolaos grew up in Denmark and spent two years at an English private school as well as serving in the British navy.

Tatiana was born as the daughter of a former German aristocracy in Venezuela and grew up in Switzerland.

She had to overcome tragedy in her childhood when her father committed suicide when she was seven years old.
