A huge photo of the Duke of Sussex, taken during his 2013 visit to America, could be seen on the wall in the background as Mr Biden chatted to the Clintons at Arlington National Cemetery. The picture shows Harry, dressed in military uniform, placing a wreath at the Tomb of the Unknown Soldier.
Royal expert Omid Scobie said on Twitter: “A blink-and-you’ll-miss-it cameo by a royal at President Biden’s #InaugurationDay visit to Arlington Cemetery. Well, kinda.
“Eagle-eyed fans were quick to spot a giant photo from Prince Harry’s 2013 visit hanging in the background while @JoeBiden caught up with the Clintons.”
Another Twitter user said: “Great day & great pic. Prince Harry in the back, the Clinton’s & President Joe Biden.”
Another royal fan commented: “Love this. Great to see Prince Harry’s presence.”
A third added: “The people’s prince.”
One more said: “Yes our #PrinceHarry featured @Biden #Inauguration2021.”
Mr Biden was inaugurated as the 46th president of the United States of America on Wednesday.
Harry is a friend of Mr Biden and his wife Jill, who have supported his Invictus Games.
Mr Biden previously joked that when his wife went to London for the event in 2014 “she spent too much damn time with Prince Harry”.
Harry and Meghan Markle are now living in America after quitting royal duties last March.
