Direct from the Crown Estates website. The Crown Estates provided income to the Monarch to run the country in the days when taxation was rare and could not provide the income needed to run the country. These days the income from the Crown Estates is dwarfed by what is brought in by taxation.
Who owns The Crown Estate?
"The Crown Estate belongs to the reigning monarch ‘in right of The Crown’, that is, it is inherent with the accession to the throne. But it is not the private property of the monarch – it cannot be sold by the monarch, nor do revenues from it belong to the sovereign."
Still on topic , what a toady , insincere , sycophantic , bed-wetting shitbag.
