Prince William and his new bride sprang a surprise, announcing they would not leave immediately on honeymoon and the prince will return to his day job as a helicopter pilot next week.
A statement from St James's Palace on Saturday said William and Kate would spend the weekend in Britain following their wedding and have a honeymoon abroad in the future but it "will not be disclosed in advance".
The prince "will return to work as a search and rescue pilot next week", it added.
The announcement appeared to be a way of throwing the media off their trail amid fears that photographers would pursue the couple wherever they chose to spend their honeymoon.
The prince is known to enjoy outwitting the media, whom he still holds responsible for the death of his mother Diana, Princess of Wales, killed in a car crash in Paris in 1997 as she was being pursued by photographers.
The prince's office stressed that the couple "have asked that their privacy be respected during the coming weekend and during their honeymoon".
The royal family is thought to be prepared to take legal action to prevent any media outlet attempting to disrupt the trip.
