Princess Anne, the Princess Royal, turns 70 on Saturday, and is set to celebrate with family in Scotland, in ‘scaled back’ celebrations.

Anne, the only daughter of the Queen and Prince Philip, has forged a reputation as one of the hardest working royals, regularly carrying out some 500 engagements every year, representing her mother.

She opted to go straight into royal life at the age of 18, missing out on university, and has developed strong relationships with many charities over 52 years.

She’s known as a no-nonsense royal who drives herself to engagements and heads straight home from glamorous events to feed her chickens.

But back in the day she was a fashion-forward young princess, and many of her looks would not be out of place in 2020.

Thanks to her portrayal in The Crown, there’s a new generation of people curious about the Princess Royal.

Yahoo UK picked seven stunning images to mark her milestone birthday.
