Britain’s beloved royal couple is taking legal action against a magazine that published photos of Catherine, the Duchess of Cambridge.

Attorneys for Prince William and Kate filed a criminal complaint on Monday against the photographer who took the shots, according to the UK Independent.

They will also be seeking an injunction against Closer magazine using more pictures  and to prevent further publication of the photographs in France.

“We can confirm that a criminal complaint has been made to the French Prosecution Department today,” said a spokesperson for Clarence House.

The photos in question show Kate sunbathing in private during a vacation at a private chateau belonging to William’s uncle in Provence, in southern France.

Some have questioned all the uproar over the images, as topless sunbathing is a commonly accepted practice in many parts of Europe.

But royal biographer Christopher Andersen told CNN the issue is less about nudity and more about privacy.

According to Andersen, William and his brother Prince Harry still blame the media for the 1997 death of their mother, Princess Diana, in a traffic accident as her driver fled paparazzi. As a result, the royal family is concerned about similar invasions, particularly if William and Catherine have a child

“This is a deterrent. They’re drawing a line in the sand,” he said.

Will and Kate have remained cool and collected throughout the storm of publicity surrounding the photos. The couple is currently on a goodwill tour of Asia related to the Queen’s Diamond Jubilee.
