Normally, any assets valued at more than £325,000 will be subject to a 40% taxation, but in a clause created in 1993, it was approved that 'sovereign to sovereign' transactions would be exempt from this.

As well as Clarence House, where King Charles and the Queen Consort are living, other properties that will be owned and managed by William under the Duchy include developments in Newquay and Poundbury and most of the land which makes up the Isles of Scilly.
How the ownership of the Duchy works has been laid out in the rules: "A charter ruled that each future Duke of Cornwall would be the eldest surviving son of the Monarch and the heir to the throne."

The Duchy generates a £23 million-a-year income, and it was a role that Charles took very seriously, working to build sustainable and profitable estates.
According to the Court Circular, William spoke to the Duchy's finance committee via video link on Wednesday, as a mark of the commencement of his new and important role.
