Prominent examples are The Right Honourable David Cameron PC MP, former Prime Minister of the United Kingdom, The Right Honourable Stephen Harper PC MP, former Prime Minister of Canada, The Right Honourable John Key MP, former Prime Minister of New Zealand, and (the late) The Right Honourable Raila Odinga, C.G.H., Former Prime Minister of the Republic of Kenya.

In the United Kingdom, the term is now given to members of the Privy Council of the United Kingdom. In effect, these are present or past members of Parliament who have served as cabinet ministers in a government.
