(JNS) “Spare,” a new tell-all, bestselling memoir by Prince Harry, Duke of Sussex, is provoking a reassessment of some of the royal family member’s previous controversies, notably his once wearing a Nazi uniform to a party.

The prince’s family is apparently displeased by being cast in such an unflattering light.

In 2005, Harry drew criticism for donning a German Afrika Korps uniform with a swastika armband to a “Colonial and Native”-themed costume party. The prince was 20 years old at the time and has since apologized, stating in a recent Netflix docu-series, “It was probably one of the biggest mistakes of my life….I felt so ashamed afterwards.”

The prince explained his efforts to learn from the mistake, “All I wanted to do was make it right. I sat down [and] spoke to the chief rabbi in London, which had a profound impact on me. I went to Berlin and spoke to a Holocaust survivor. I could have just ignored it and gone on and made the same mistakes over and over again in my life. But I learned from that.”

In the Netflix series, the prince attributes the donning of the costume to his family’s “huge level of unconscious bias.”
