The will of Prince Philip, the late husband of Britain's Queen Elizabeth, will be sealed and remain private for at least 90 years to preserve the monarch's dignity, a judge at London's High Court has ruled.

Philip, the Duke of Edinburgh, who had been married to the 95-year-old British monarch for more than seven decades, died at the age of 99 at his wife's Windsor Castle home to the west of London on April 9.
