According to the bottom of the page of this url
https://www.bbc.co.uk/news/uk-51185628Currently, 95% of the couple's income comes from Prince Charles's income from the Duchy of Cornwall, a vast portfolio of property and financial investments, which brought in £21.6m last year.
....
It is understood the couple will continue to receive money from Harry's father under the new agreement, although it is unclear whether this will come from the Duchy, his personal wealth, or a combination of the two.
However, the pair will stop receiving money from the taxpayer-funded Sovereign Grant, which makes up the other 5% of their income.So not as if he is forgoeing much is he? I was of the impression he might have to sign on
And the Duchy of Cornwall is a quasi public/private entity and Charles probably offsets any payments to Harry against tax? So it seems to me all a bit of a fiddle.
I hope we are starting to see the dismantling of the monarchy - Charles will be the last with William is it over seeing boarding up Buck. Palace, prior to be turned into a museum ( or a 10 star hotel
) ? That will be a day to celebrate?
