Ivory Bill

My Lords, I support the Bill very much, but will the Chief Whip say why it was necessary to get the consent of the Queen? Is it because she is worried about the value of the ivory that she might own if it were sold, or is she worried about elephants? They are both good causes, but it seems a bit odd. We should be pleased to have her consent, but does the Duchy of Cornwall own ivory? Why did we not seek the consent of the Duchy as well?
