Spanish Crown Princess Leonor, 15, was first seen in public alone without her parents.

The princess, irradiated in a knee-length dress, attended the 30th anniversary of the Cervantes Institute in Madrid, the capital of Spain.

According to People magazine, Leonor read the same excerpt from the Spanish Constitution at the event, which he read when he gave his first public speech a couple of years ago.

The Daily Mail describes the appearance of the Crown Princess as confident and professional.

The performance had gathered a large audience at the venue, cheering for their princess.

Leonor and his little sister, Princess Sofia, 13, have lived a well-protected life, for King Felipe VI, 53, and Queen Letizia, 48, are very protective of their daughters.

Princesses have usually only been seen in public in official photographs as well as at Spanish National Day celebrations in October.

Over the past couple of years, however, young princesses have gradually been given more and more representational roles and responsibilities.

Leonor will in time follow his father, King Felipe, to the throne, unless the royal couple gets a son, which would change the order of inheritance.

People and the Daily Mail say Leonor is heading abroad to study, as has long been expected.

According to press reports, he has a place to study in Wales at the internationally acclaimed UWC Atlantic College, where he has also studied with other European royals.

The Crown Princess degree is for two years, and the royal couple personally pays their daughter a course fee of £ 67,000 (approximately € 77,800).

King Felipe himself first studied law at the University of Madrid, after which he completed his master’s degree at the University of Georgetown in Washington.

Princess Leonor speaks fluent English in addition to her mother tongue, and despite her young age, she also studies Mandarin Chinese, French and Arabic.
