Prince Philip, the late husband of Britain's Queen Elizabeth II, will be laid to rest today in an intimate service attended by 30 people including members of the royal family.

Philip, also known as the Duke of Edinburgh, died at the age of 99 on April 9 in Windsor Castle. He was the nation's longest-serving consort -- the name used to describe the spouse of a reigning monarch -- and had been married to the Queen for 73 years.

His death has left a "huge void" in the "stoic" Queen's life, her son, Prince Andrew has said.

The funeral will be a "profound" moment for the Queen to say goodbye to "someone to who she was married for 73 years," Justin Welby, the Archbishop of Canterbury, told the BBC.
