All Queen Elizabeth II's grandchildren - eight in total - will stand vigil by her coffin at Westminster Hall in London on Saturday evening, a royal expert confirmed to Fox News Digital on Friday.
Harry, who served 10 years in the British Royal Army, will wear his military uniform for the event, despite initial speculation that he would not be allowed to.
"I am glad the King thought better of it," Shannon Felton Spence, a royal expert, told Fox News Digital. "It's the right thing to do. The Queen was immensely proud of Prince Harry's service, as his Granny and as his Commander-in-Chief."
