King Charles has enough experience of giving speeches by now to have fine-tuned the elements needed - including a sprinkling of humour. He didn't overdo it when he gave a speech to the US Congress on 28th April and in amongst his powerful reflections about the current state of the world and UK/US relations, he also mentioned a strange royal tradition.
I'd totally forgotten this was a thing and to many people it could sound like an exaggeration or a myth, but King Charles confirmed that a "hostage" is still taken when he addresses Parliament.
