Princess Charlene's protocol error during historic meeting

Princess Charlene of Monaco has faced accusations of breaching royal protocol during a historic meeting with King Felipe VI of Spain and Queen Letizia in Madrid. On Monday, Charlene, 48, and her husband, Prince Albert, were welcomed by Felipe and Queen Letizia at the Palace of Zarzuela in the Spanish capital for their first ever official visit to the nation. Marking a significant diplomatic milestone for the Monegasque royal couple - all eyes were on the two couples as they began a tour of the city's Royal Botanical Garden. Yet eagle-eyed onlookers noted that Charlene may have made an unfortunate protocol faux pas during the poignant meeting - by curtsying to both Felipe and Letizia.
