Kate Middleton and Prince William unexpectedly lose longtime trusted staffer

Kate Middleton and Prince William’s inner circle just got smaller.

The Prince and Princess of Wales are unexpectedly losing their longtime trusted staffer Natasha Archer, after more than 15 years of working together, according to People.

Archer reportedly made the decision to leave Kensington Palace to set up her own private consultancy.

The outlet reported that the Waleses’ household gave Archer their well wishes ahead of her new business venture.

Page Six reached out to Kensington Palace for comment but did not immediately hear back.

Archer began her tenure in 2010 as a personal assistant to the royal couple, both 43.

Throughout the years, she grew close to Middleton and became her unofficial stylist.

In 2014, Vanity Fair spoke to an insider about how Archer helped Middleton come out of her style shell.

“Initially, Kate was a reluctant fashion icon, but now she enjoys it. Tash helps source some of the clothes,” the source told the outlet.

“She shops a lot for Kate online, and calls in hundreds of dresses for Kate to try on. She has persuaded Kate to take some more risks. The hemlines are shorter and Kate’s really pushing the boat out in the fashion stakes.”

Last summer, Middleton promoted Archer to be her and William’s senior private executive assistant.

A source told the Daily Mail at the time, “Natasha deserves this boost – she’s unfailingly discreet and loyal to Kate. The salary boost will be welcome too.

“This appointment means we can expect to see Natasha by Kate’s side for years to come.”

The insider added, “It seems to be Kate’s way of thanking her for her loyalty.”

Before joining William and Middleton, Archer worked in the private office of the Duke and Duchess of Gloucester.

Archer is married to Getty royal photographer Chris Jackson, with whom she shares two children.
