It appears that Prince Harry will not be in the United Kingdom next month to celebrate Queen Elizabeth II's Platinum Jubilee.

The Duke of Sussex is expected to have a busy month in June, as he has allegedly committed to playing a complete season of polo in California, which will take place over the four-day long weekend in the United Kingdom. 

Last week, the 37-year-old former senior royal was pictured participating in polo, and he was anticipated to continue playing the sport with his Los Padres colleagues for the remainder of the 12-goal polo season in Santa Barbara. 

The claims were made on Twitter by Omid Scobie, the Duke of Sussex's unauthorized biographer, who stated that Prince Harry will be competing in the Folded Hills Pope Challenge between May 9 and 15, the Lisle Nixon Cup between May 20 and 29, and the Cheval Athletics USPA Intra-Circuit from June 3 to 19. 

Because of his dedication to the tournament, it's possible that the father of two will be unable to attend his grandmother's large celebration. He may, however, be able to participate in the major celebrations if his schedules permit it to do so. 

At either end of the festival, numerous members of the Royal family are anticipated to appear on the balcony of Buckingham Palace. The Platinum Jubilee festivities will begin on June 2 and last through June 5, with several members of the Royal family expected on the balcony of Buckingham Palace. 

The Queen's appearance on the balcony of the renowned palace, which might signal the culmination of her Platinum Jubilee festivities, is believed to be "by no means definite," according to a source close to the situation.

Meanwhile, the Telegraph noted that polo tournaments in Santa Barbara are often held on Friday and Sunday afternoons in the city of Santa Barbara. However, it is presently uncertain if the Duke of Sussex has already informed the palace of his plans or whether he has yet to do so. 

According to the Daily Mail, Prince Harry might return for Trooping of the Color on Thursday's celebrations, although he has not provided any indication that he would be there for the occasion. 

Besides that, he stated that he would not be resuming travel to his native country until his family is secure, and that there will be significant improvements to their security measures. 

However, for major occasions like as the Queen's Platinum Jubilee, Prince Harry and Meghan Markle would be protected to the fullest extent possible, as would other royals.
