In 1788, pending the great question of the regency, it was contended on that side of the House of Commons from whence extension of royal prerogative was least expected, that from the moment parliament was made acquainted with the king’s incapacity, a _right_ attached to the prince of Wales to exercise the regal functions, in the name of his father. On the 15th of December, the duke of York rose in the House of Lords, and a profound silence ensued. His royal highness said, that though perfectly unused as he was to speak in a public assembly, yet he could not refrain from offering his sentiments to their lordships on a subject in which the dearest interests of the country were involved. He said, he entirely agreed with the noble lords who had expressed their wishes to avoid any question which tended to induce a discussion on the rights of the prince. The fact was plain, that no such claim of right had been made on the part of the prince; and he was confident that his royal highness understood too well the sacred principles which seated the house of Brunswick on the throne of Great Britain, ever to assume or exercise any power, _be his claim what it might_, not derived from the will of the people, expressed by their representatives and their lordships in parliament assembled. On this ground his royal highness said, that he must be permitted to hope that the wisdom and moderation of all considerate men, at a moment when temper and unanimity were so peculiarly necessary, on account of the dreadful calamity which every description of persons must in common lament, but which he more particularly felt, would make them wish to avoid pressing a decision, which certainly was not _necessary_ to the great object expected from parliament, and which must be most painful in the discussion to a family already sufficiently agitated and afflicted. His royal highness concluded with saying, that these were the sentiments of an honest heart, equally influenced by duty and affection to his royal father, and attachment to the constitutional rights of his subjects; and that he was confident, if his royal brother were to address them in his place as a peer of the realm, that these were the sentiments which he would distinctly avow. * * * * *
