Prince Harry was seen in public Thursday for the first time since his stunning announcement that he was quitting the royal family.

The Duke of Sussex was spotted staring intently at his phone in the back of a car as he was driven into Buckingham Palace for his first official royal engagement since Megxit.

The 35-year-old prince has managed to keep a low-profile in the week since the bombshell news, sneaking into a historic royal summit Monday — while wife Meghan Markle has made public appearances at a series of women’s group meetings while staying with baby Archie in Canada.

Royal biographer Angela Levin told Sky News that the world would be seeing “a sad Harry who puts on a good face because of his sense of duty.”

Harry is due to host the draw for the Rugby League World Cup, as proudly confirmed by the Royal Family on its official Twitter account — which notably referred to him as His Royal Highness in another message.

Harry and Meghan’s titles and roles in the family are understood to be part of ongoing debate during the “period of transition” the Queen granted the couple who she says “wish to live a more independent life.”

Harry also appeared in a video Thursday supporting a “Mental Fitness Charter” aimed at rugby players — with some potentially telling quotes that could relate to his own drama.

He called rugby a community that “takes care of its own” and advised players not to just “grin and bear it” and hide their feelings.
