Prince Charles is facing calls for his Duchy of Cornwall estate to pay more tax on the large stretches of land it owns across the south west.
The issue will be raised by a committee of MPs shortly.
The committee's chair says she wants to know if the Duchy - which doesn't pay either Corporation Tax or Capital Gains Tax - is contirbuting its fair share.
The Duchy defends its position and points out that the Prince does voluntarily pay income tax.
