I refer the honourable gentleman to the question I asked some moments ago.
L to the O to the L (I is well street, innit). Got to love the ridiculous anachronisms of tradition that still make our Houses of Parliament look like a laughing stock sometimes!
Can I indulge in an aside here, by way of explanation?! Pretty please!! You can stop reading now if you don't want to know where that phrase comes from (well, actually since none of this post is on-topic you could have stopped reading at the first "L").
Anyhow, every week (it used to be twice a week), the Prime Minister has to answer questions on the floor of the House of Commons (UK's lower parliament). Questioners are selected by the Speaker, on topics that are not known in advance to the PM (the leader of the main opposition party by convention gets a set number of questions automatically, as do leaders of smaller parties on rotation I believe).
So.... PM's Questions always used to begin by the first questioner standing up in the House and asking the PM a fixed, anodyne question about what he/she had been doing that day, and what his/her plans were for the rest of the day. The PM would then reply: e.g. "This morning I chaired a cabinet meeting, and had meetings with advisers. This afternoon, I plan to visit a hospital in Southampton, then I have an official dinner with the Prime Minister of Sweden".
After the PM's explanation of his/her schedule, the first questioner would then be allowed to ask what was called a "supplemental question" - which was the question that (s)he actually wanted answering. E.g. "Could the Prime Minister tell us why 200 of my constituents in the steel industry are about to lose their jobs"? And the PM would answer (or artfully evade) that question.
But for the second questioner onwards, protocol dictated that they all had to formally pretend to ask the PM the same anodyne opening question that had been asked by the first questioner. Except that the explicit asking of this question didn't even have to happen - but the PM had to PRETEND the question had been asked! So, when the speaker called the second (and subsequent) questioner to stand, there was an immediate presumption that the "PM's whereabouts" question had been instantaneously re-asked.
So the PM would start his/her interaction with questioners 2+ by pretending that he/she'd been asked again about his/her movements for the day. And tradition dictated that (s)he would say the precise words "May I refer the honourable gentleman/lady to the answer I gave some moments ago" (i.e. referring to his/her earlier answer to the first questioner's opening question). The questioner could then ask a supplementary question in the same way as the first questioner had done.
This ridiculous and archaic "tradition" was thankfully abolished as part of the general reform/updating of PMQs, but the phrase remains well-known - partly as a self-mocking reminder of how stupid some (but not all) traditions can be.
Indulgence over - just thought some of you might be vaguely interested in a bit of trivia.
