Back to the original fascinating question.
There are a few cultural differences here. For example, In the US, President is a title, e.g. President Bush, President Obama. And they keep their title even after their presidency is over. (So the Clinton’s could possibly be, instead of Mr and Mrs, President & President Clinton). In the UK, Prime Minister is a position. The proper title is The Right Honourable (Rt Hon David Cameron, or Rt Hon Theresa May)(Right Honourable is actually a title conferred on members of the Privy Council, but that’s another discussion). At the end of their premiership, they retain the Rt Hon, and may be referred to as former Prime Minister. I notice that Mrs Clinton is referred to as Secretary Clinton, which would not happen in the UK.
In the Jewish world, as far as I am aware, we in the UK have a unique thing in that a dayan on a beis din gets the Dayan as a title, e.g. Dayan Dunner, as opposed to, let’s say, Rabbi Braunstein who is known as Rabbi. So, when referring to the Chazon Yechezkel, a Briton would say Dayan Abramsky, whereas anyone else would call him Rav Abramsky. The Minchas Yitzchok is known here as Dayan Weiss, but in Eretz Yisroel, as “Harav Weiss der gaavad, (nein, nisht der heintiger, der alter vos hot geshriben Minchas Yitzchok)”.
