PS I could add that I suspect that for the past month he's been on strike in support of this, but the evidence for whether he's actually at work or not is inconclusive.
This is interesting. On my first visit to London in 1980, I happened across the Court Circular/Royal Diary and was impressed at how many engagements the Queen and Prince Phillip conducted... generally more than one a day, if I remember correctly. Reading the quoted comment, I wondered if the same information is published for current royalty. It is, and a quick search of the various calendars was very interesting:
The King - 1 upcoming event, July 24 (calendar search was 20/07/2023-20/07/2024)
The Queen - no upcoming events
The Prince of Wales - 2 upcoming events in New York in September
The Princess of Wales - no upcoming events
The Duke of Edinburgh - 5 upcoming events between now and September
The Duchess of Edinburgh - no upcoming events
The Princess Royal - 23 upcoming events between now and October (with up to 3 events on a single day. On the 7th of September, for example, she's in Welwyn Garden City, then 2 events in London, including a dinner.)
The Duke of Gloucester - 7 upcoming events between now and September
The Duchess of Gloucester - 3 upcoming events between now and September
My grandparents were from Cornwall, so I inherited a bit of their support for the monarchy (even though they emigrated to the US, where my mother was born). But one of the justifications for the cost of the royal family to taxpayers is they provide a visible yet non-partisan representation of the country. This implies a certain responsibility to actually provide that personal presence. Perhaps one way to tighten the purse strings would be "No play, no pay".
