Blondiescot

How would you get rid of them ? who would you want to get rid of ?
I'm thinking along the lines of what maddyone said. If we have to have a royal family at all, there should be a king (or queen) plus their spouses and children, full stop. No need for any others. I appreciate that there are, at present, some hard-working members of the RF, but once they go, it should be pared right back to the bare minimum.
But how would you "get rid of them" Blondiescot? You can't have them all sterilised at birth, that wouldn't be ethical. If they produce children, those children are part of the family, as much as your grandchildren, nephews and nieces are part of yours.
If you mean, you wouldn't have them supported by the state, very few of them get anything. If you mean, you wouldn't have them as patrons of charities, members of the boards of prestigious companies, and so on, that is up to the organisations to choose their officers, not up to the law to ban them. It is the same for opening new bridges, presenting awards etc. If a company wants to ask someone to cut the ribbon to open their new hospital or school, they don't have to ask government permission.
Recently, the Queen has cut back on her engagements - she is getting older after all - so younger members of the RF have been asked to do more things and be more visible. Under Charles, and then William, that need not be the case with younger heads of state.
