Their behaviour is entirely consistent, as is that of the palace. I'm getting a strong sense of deja vu of 2020, a grandiose statement released, without consultation, claiming to be Internationally Protected Persons, claiming they would be half in and half out, would make millions, would live a life of service etc etc. The palace said no to everything, gave them a year to change their minds and made it clear they are making their lives abroad and no longer working members of the family.
2026, grandiose briefing they are returning to visit charities, send the children to school, run businesses, etc etc. It's entirely consistent that they didn't tell Charles in advance and now the palace makes it clear they are not working royals and nothing has changed.
The talk of rival courts is rubbish. One court is The Court of St James, containing the Head of State, his heir and those who represent him at home and abroad. They host other Heads of State, support charities, the military, national sports teams, undertake diplomatic visits on behalf of government.
The other "court" is a couple of minor royal/ celebrities, who occasionally visit charities and talk about themselves, make jam, tell repetitive stories of events at least 6 years ago, and have no influence or political power. They couldn't even be top dogs in Hollywood.
The only rivalry is in the pages of the tabloids and in social media people who need revenue and clicks and use celebrities for money. Only one side thinks it's a competition, the other know that they don't need to compete, or even acknowledge the other's PR stunts.
