Live on air walkouts have produced some classic television. My first experience of a walkout was by Denis Healey on Breakfast television and I wasn’t even asking the questions. He took exception to an enquiry from my colleague, Anne Diamond ,about his wife’s private medical treatment. The then Shadow Foreign Secretary stood up, dragging the sofa with him by his mike cable, bellowing “You’re a s***, and you’re a s*** and TV-am’s s***.” Cut to commercial break. Then he punched me. This was in front of the next guest, the gossip columnist Nigel Dempster, so there was no chance of keeping it out of the papers.
