Duchy Of Cornwall

[Barsel]

Was watching Prince Charles inside the Duchy of Cornwall on Thursday night and from what I can make out, he uses the revenue from that to support himself and Camilla plus the Cambridges and their children and the Sussex's and their child. Do they get money from somewhere else as well? When Charles hands it over to William, will William have to pay for the upkeep of Camilla (if Charles goes first) and also Harry, Meghan and Archie, or will he just have to use it for himself, Kate and their children?

Thanks for all your answers. x
