Northern Ireland (Executive Formation) Bill

My Lords, it is always a pleasure to follow the noble Lord, Lord Forsyth, who is one of the most persuasive debaters in this House, as he was in the other place. However, I am concerned by what he said a moment or two ago. He seems to have forgotten that we do not have an executive form of government in this country. If it is Mr Johnson who becomes Prime Minister, that is what he becomes—Prime Minister, not president of the United Kingdom. The role of the Prime Minister is surely to face Parliament, the House of Commons in particular, persuade it if he can and serve it if he retains its confidence. If he loses its confidence, it becomes his duty to resign, which could happen more quickly than some, particularly Mr Johnson, think.
