Move over, Kate! There's a new style queen (quite literally) on the scene...
We imagine that the Duchess of Cambridge is shaking in her trusty nude court shoes today as a new pretender to her 'most stylish royal' crown emerges.
News that King Juan Carlos of Spain is to abdicate has turned the eyes of the world on his son, Prince Felipe, who will become the country's new king - and also on new queen-to-be Princess Letizia.
And Kate has cause to worry - with a natural style eye, Letizia nails everything from off-duty dressing (thanks to a wardrobe of sweet day dresses and casual separates) to big event eveningwear, sweeping into the palace in everything from statement-making ball dresses to a formal-yet-foxy jumpsuit.
