Why do  so many campaigning politicians, notably John McDonnell, insist on opening their presentations with "What we are saying is......................" instead of simply saying it?

"Sometime between the 24/04/17 and 10/05/17 the railway bridge at Buckleaze Lane in Pewsey has been gratified (sic). A large SD tag has been sprayed onto the bridge and on the opposite side in white "YOLO"."

I despair. 😕

Why do so many TV programmes need two presenters sitting side by side and speaking sentences in turn, the non-speaker staring blankly into the camera or inspecting their companion's ear wax? It's daft. It won't be long before they are speaking each word in turn.

Why does the farming industry, when referring to pesticide and fertiliser inputs, insist on using the phrase "dose rate"? Isn't it either a dose or a rate?
