PRINCESS Kate’s close ally and “tower of strength” colleague has handed in her notice after 15 years.

Natasha Archer has worked with the Princess of Wales as her PA and stylist since 2007, and has been behind her iconic royal looks over the years.

Now, Natasha is said to be leaving Kensington Palace to set up her own private consultancy firm.

During her time as a royal staffer, she is said to have grown very close to Princess Kate and recently became the senior private executive assistant to her and Prince William.

Natasha and Kate are said to be parting on good terms, with the royal household wishing her the “very best” in her new business, according to People magazine.

The Princess of Wales is said to have relied on her stylist for support as she underwent cancer treatment.

Royal biographer Claudia Joseph, author of Kate: The Making of a Princess, told Fabulous: “Natasha has been at Kate’s side since she joined the Royal family and will be a tower of strength for her as she fights her battle against cancer.”

Kate underwent the “planned major abdominal surgery” in January 2024 at the London Clinic in Mayfair, and Natasha was among the trusted people of her loyal inner circle who visited her.

Claudia added: “She was one of a handful of people who visited the Princess at the London Clinic, and is, no doubt, available to her day and night, whenever she wants a chat.

“Natasha, who is five years younger than Kate, has been in the Princess’s orbit for more than 13 years and has witnessed all the key events in her life: she has been at her side for Royal weddings, births and overseas tours, she visited Kate at the Lindo Wing, at London’s St Mary’s Hospital, after the birth of her children.”

Her dedicated service was rewarded in December 2018 when she was honoured with the Royal Victorian Order for her hard work.

The stylist – who is married to royal photographer Chris Jackson – largely keeps out of the public eye and is said to have a lot in common with Kate.

Claudia continued: “The couple, who wed in 2017 at a medieval mansion near Bordeaux, are naturally discreet so they fit in with William and Kate’s ethos.

“The two women share a close bond as they have a lot in common: they both went to boarding schools, share a love of art and fashion, and are mothers – Natasha’s oldest son Theo is just a few months younger than Prince Louis.”

According to Grazia, the late Queen requested that Natasha was hired as Kate’s stylist to make her wardrobe look “regal”.

A source said at the time: “Natasha’s main role is as a PA, but over the last few months she has assisted Kate as a style adviser.

“Natasha and Kate get on very well. She has always supported and advised Kate – and the Duchess loves Natasha’s style, so it seemed like an obvious appointment.”

Natasha has been responsible for some of Kate’s most iconic fashion looks, with Claudia adding that she has encouraged Kate to “experiment with her wardrobe and transform her from Sloane Ranger to style icon.”

The royal biographer added: “It is she who introduced Kate to the designer Jenny Packham, who is one of her favourites, and she who persuaded her to try shorter hemlines, culottes and wide-legged trousers.

“She scours websites for the latest trends, ordering in clothes, ironing the Royal wardrobe and dragging around her wheelie suitcase.

“She has even been known to touch up Kate’s make-up on the plane and reputedly helped William spruce up his wardrobe after he was criticised for looking like an ‘estate agent’.

“Apparently, she got rid of his white Asics trainers.”

For the occasion she donned a £250 polka dot midi dress by one of Kate’s favourite brands, LK Bennett.
