According to the Press Association, Mr Justice MacDonald pronounced the decree absolute at a hearing at the Family Division of the High Court in London.

The news agency said that the judge analysed arguments over money at a private trial from October and a ruling from December 2018. He ruled that Tessy Antony and her two children from the marriage with Prince Louis would live at the property the couple shared when married.

The prince was ordered to pay a “nominal” maintenance and pay child maintenance of £4,000 per year per child, the PA reported.

Tessy, who was formerly a soldier in the Luxembourg army, met the third son of Grand Duke Henri and Grand Duchess Maria-Teresa in 2004. The couple married in 2006 but the relationship broke down during the summer of 2016, the agency reported.

Since then the two became locked in a battle regarding financial arrangements. Mr Justice MacDonald was quoted as saying on Thursday that the dispute was a “sad case” involving a couple who were determined to marry for love and had been happy before their “fairytale” soured.
