Prince Harry and Meghan Markle’s attendance at Queen Elizabeth II’s Platinum Jubilee has been called into question over the duke’s polo commitments.

Harry has signed up to Los Padres, his local team in California, and will play a season at Santa Barbara Polo & Racquet Club, not far from his home in Montecito.

They will play several tournaments in spring and early summer, including the Cheval Athletics USPA Intra-Circuit, which runs from June 3 to June 19.

The date covers most of the Platinum Jubilee long weekend, which runs from June 2 to June 5. However, it is not clear when Harry’s matches would be or if he could do both.

Omid Scobie, author of Harry and Meghan biography Finding Freedom, wrote on Twitter: “Prince Harry will play the entire 12 goal polo season at Santa Barbara with his #LosPadres teammates (@nachofigueras, @kekomagrini, Juan Guerrero).”

The confusion adds to existing uncertainty about Harry’s attendance at the jubilee, which celebrates 70 years of the Queen’s reign.

The prince filed a lawsuit against the U.K. government for removing his police protection and a legal representative said in January that he does not consider it safe to return without Metropolitan Police bodyguards.

Harry told NBC’s Hoda Kotb during his Invictus Games tournament in April that he might not be at the jubilee as a result of the dispute.

He said: “I don’t know yet. There’s lots of things with security issues and everything else. This is what I’m trying to do, trying to make it possible that I can get my kids to meet her.”

Archie Mountbatten-Windsor, who turns three on May 6, has not seen the Queen since he was a baby, while Lilibet Mountbatten-Windsor, 10 months, has never met the Monarch, nor her grandfather Prince Charles.

Lili was named in tribute to Elizabeth, whose nickname within the family is Lilibet.

Meghan made her first visit to Britain since quitting royal duties and, together with her husband, had tea with Queen.

The couple also had a meeting with Prince Charles and Newsweek has been told the future king enjoyed seeing both Harry and Meghan and hearing news of their children.

However, any hopes the visit represented an olive branch took a dent when Harry swerved a question on whether he missed Prince Charles and Prince William.

Asked a direct question about it, Harry told Kotb: “I mean… at the moment, I’m here focused on these guys [at the Invictus Games] and these families and giving everything I can, 120 percent to them to make sure that they have the experience of a lifetime. That’s my focus here.”

He also called into question the people in Elizabeth’s circle in what was widely interpreted as a dig at the palace staff he has clashed with before.

The duke said: “It was just so nice to see her. She’s on great form. She’s always got a great sense of humor with me and I’m just making sure that she’s, you know, protected and got the right people around her.”

He added: “Both Meghan and I had tea with her so it was really nice to catch up with her. You know, home—home for me, now, is, you know, for the time being, in the States.

“And it feels that way as well. We’ve been welcomed with open arms and we have such a great community up in Santa Barbara.”
