Prince Harry and Prince William may be siblings, but they couldn’t be more different from each other when representing Queen Elizabeth II.

In the book “Harry: Life, Loss, and Love” royal author Katie Nicholl detailed how Prince Harry got choked up in public while talking about his beloved grandmother.

While the new dad was in Brazil in 2012, Prince Harry was in constant communication with Prince William. He was also seeking advice from his older brother and keeping him updated on how things were going during his royal tour.

Following his engagement, Meghan Markle’s husband said that the tour was both fun and emotional. Nicholl quoted Prince Harry as saying that he had no idea how much warmth there was toward the Queen in Brazil.

“To me, that’s been very humbling, and I was actually quite choked up, seeing the way that they are celebrating her 60 years,” Prince Harry said.

Back in Britain, home courtiers praised Prince Harry for his tour, which they dubbed as a diplomatic tour de force. The Queen also praised her grandson following his excursion.

“The international media had also deemed the trip a triumph, and the British newspapers described it as the making of a modern Prince,” Nicholl said.

But following the engagement, the public couldn’t help but compare Prince Harry to Prince Charles and Prince William. Nicholl said that the Duke of Sussex managed to prove how relaxed and spontaneous he was compared to his sometimes-reserved father and brother. Prince Charles and Prince William usually appeared to be buttoned up and limited by royal protocol.

In related news, Prince Harry also made headlines this week after it was revealed that his son, Archie Harrison Mountbatten-Windsor, would share a special bond with the Queen. This is because Prince Harry also has a special relationship with his grandmother.

Former royal butler Grant Harrold said that the Queen tends to let her guard down a bit whenever she’s with Prince Harry.
