Oh. Right. My information is out of date: "The Queen’s youngest son and his wife, Sophie, Countess of Wessex, spend most of their time in Surrey at Bagshot Park with their two children. Prince Edward leased the property a year before getting married." was in 2018. They actually live in the Mansion House, which he paid more than a million quid to renovate, and pay £90,000 a year for it. So no, not "given".
And he gets nothing from the civil list, because it no longer exists: he lives on his mother's charity, in effect. That seems to me to be quite a long way off £14,000,000 to do as he wants with.
I have just noticed that Edward has got married once and stayed married to the same person for over twenty years, which is better than his siblings have managed, or his aunt. And when he did cut loose from the Firm, he got an actual job, and didn't just fanny about being a Celebrity. I'd say he was probably the best of that somewhat ropey bunch.
