Italian parents have been told they must change their baby daughters unique name or the judges would choose a new one for her.

Vittoria and Luca named their daughter Blu, totally unaware that they were going to fall foul of the Italian court system.

The Mirror reports: Luca picked the name saying it stood for ‘bella luminosa unica’ – which translates as beautiful, vibrant and unique.

But laws in Italy state that infants must be given a gender-appropriate name.

Luca told Italian newspaper Il Giorno : “If we don’t come up with an alternative name, a judge will chose it for us.”

And Repubblica reports that Luca described the case as “absurd discrimination”.

The child’s name is the Italian spelling for blue, and the couple argue that many parents – including Jay-Z and Beyonce – have named their children after colours.

The celebrity couple’s oldest daughter is called Blue Ivy.

Italy’s national statistics agency, Istat, has said there were six girls named Blu in 2016, and five the year before that, The Local Italy reports.

In Milan alone, there are two girls called Verde, which means green in Italian.

The court case is happening because of a presidential decree which was introduced in 2000 – and a couple from Florence were hauled in front of a court in 2012 for naming their daughter Andrea.

Although this a popular girl’s name in many English-speaking countries, it Italy it is generally a name given to boys.

But the couple won that case, after the court initially said the child should be renamed Giulia.
