—and there is nothing pompous about the point of order you have raised. Thank you for giving notice of your intention to do so.
The document, “Rules of behaviour and courtesies in the House of Commons” deals with this exact matter. When a Member visits another Member’s constituency, except on a purely private visit—we all know what that entails—they should take reasonable steps in advance to tell the Member in whose constituency the visit is taking place. That guidance also states that
“failing to do so is regarded by colleagues as very discourteous.”
The guidance applies to Ministers as well as to other Members. Indeed, the “Ministerial Code” also states that
“Ministers intending to make an official visit within the United Kingdom must inform in advance, and in good time, the MPs whose constituencies are to be included within the itinerary.”
I trust that Ministers on the Treasury Bench will make sure that this is brought to their colleagues’ attention, but I should also make it clear that Mr Speaker and I expect all Members—not just Ministers—to inform their colleagues of such visits. Not to do so is discourteous.
