Italian magazine "Chi" on Wednesday (February 13) published photographs of the pregnant Duchess of Cambridge wearing a bikini on holiday in the Caribbean, angering the British royal family and reigniting a debate over privacy and freedom of the press.

The six-page insert, headlined "Kate & William - Honeymoon for three," shows the former Kate Middleton walking with her husband Prince William on a beach on the island of Mustique.

The same publication ran pictures last September of the princess sunbathing topless on holiday in France, raising questions about media intrusion into the lives of one of the world's most famous couples.

The magazine's publication of the topless pictures last year against the couple's wishes was condemned by British Prime Minister David Cameron. It stirred memories of the world media's relentless pursuit of William's mother, Princess, Diana who died in a car crash in Paris in 1997 as she was being chased by paparazzi.

The couple are expecting their first baby in July.
