Assistant Chief Constable Sarah Hamlin, who was responsible for protecting the Duke and Duchess of Cambridge — Prince William and Kate Middleton — took to Twitter to announce that she has quit from her role.

In a series of posts, Hamlin said that her "values no longer fit the org" and "she cannot make a difference." Hamlin had served Norfolk Constabulary since 1986 and was paid about £100,000 a year.

"After 30 years @NorfolkPolice I've resigned to the fact that my values no longer fit the org. I can't make a difference, support front-line," Hamlin tweeted. "And so I wish colleagues & friends all the best. Let's hope #policing can recover & that officers & staff welfare is prioritised," she wrote on Twitter.

"To clarify I am retiring! Looking forward to spending time with family & friends. Playing golf & kayaking!"

Following her tweets announcing the retirement, a few asked her why she tweeted about "values no longer fit the org." She, however, did not respond to the requests on Twitter. She later issued an official statement clarifying that she enjoyed her job and took retirement to spend more time with her family.

"I've had a fantastic career and thoroughly enjoyed my 30 years with Norfolk Constabulary and latterly in also working with the Suffolk Constabulary," her official statement read.

"I have many fond memories and without doubt, these are the best forces I could have wished to work with. I consider though that now is the right time for me to retire to spend more time with family and friends as I look to pursue my other dreams."

Hearing of her resignation, colleagues from both Norfolk and Suffolk police paid tribute to the "significant contributions" Hamlin made during her career spanning 30 years.
