What happened to an MP who brought the royal family into a House of Commons debate?
Short answerInvoking the royal family breached a strong constitutional convention and could endanger the MP's career while creating trouble for the entire party.
NotesHouse of Commons convention kept the royal family outside ordinary partisan argument. Bringing the monarchy into a debate could damage the MP's career and create trouble for the entire party because the institution was supposed to stand outside politics. Many MPs had also served long careers as naval officers, giving parliamentary naval debate a substantial base of professional experience. The separation appears in ceremony as well, including the Commons closing its doors to a messenger from the House of Lords.
