Why is The Prince of Wales asked for his approval on various Government bills?
It is a long established convention that The Prince, as Duke of Cornwall, is asked by Parliament to provide consent to those bills which Parliament has decided would affect Duchy of Cornwall interests. The same process is followed with regards to The Queen providing consent to bills that would affect Crown interests. In modern times, neither the Sovereign nor the Duke of Cornwall has ever refused to consent to any bill affecting Crown or Duchy of Cornwall interests. Every instance of The Prince’s consent having been sought and given to legislation is a matter of public record.
