The government directed the RF to attend a pantomime? Really??
Yes the meetings with heads of state tend to be government-directed. These are ones the Queen tend to do although other royals do get involved.
The kind of engagements the Queen does will need briefings. But not the other types.
Taken from most recent Court Circular -
The Duke of Gloucester, Grand Prior, the Most Venerable Order of the Hospital of St. John of Jerusalem, this morning visited the St. John Ambulance Training Centre, Harry Crook Centre, Raleigh Road, Bristol, and was received by Her Majesty's Lord-Lieutenant of the County and City of Bristol (Mrs. Peaches Golding).
What briefing is needed apart from who different people are. Maybe a very short brief on St Johns Ambulance Service.
His Royal Highness afterwards presented The Queen's Award for Voluntary Service to Mothers for Mothers, New Fulford Centre, Gatehouse Avenue, Bristol.
Short brief on what the award is. But he is presenting it, that is all.
The Duke of Gloucester this afternoon visited Bristol Water, Bridgwater Road, Bristol, to celebrate their One Hundred and Seventy Fifth Anniversary.
Short brief on who Bristol Water are and maybe a few intelligent sounding questions to ask.
The Princess Royal was present at the Service of Thanksgiving for the Life of Major Lord Patrick Beresford which was held at the Guards Chapel, Wellington Barracks, London SW1, today.
No briefing necessary unless she has no idea who he is.
Her Royal Highness, Colonel-in-Chief, Royal Corps of Signals, this afternoon visited 14th Signal Regiment (Electronic Warfare) at Cawdor Barracks, Brawdy, Haverfordwest, Pembrokeshire.
Very minimal briefing
By the way above engagements are pretty standard. Anne does loads of worthy engagements. Andrew always did fun things like going to golf clubs and dinners. Queen does a mixture of worthy and clearly government engagements. William and Catherine do little and have a fair amount of phone or zoom calls as engagements unless it is a fun thing. Charles does some worthy stuff as above.
The Queen and Anne are the only ones though who really do the work. I would be happy if Anne was going to be our new Queen. She seems to be cast in the same mode as the queen.
