Talking of Miliband's egging yesterday, the throwing of another once provided voters with one-off evidence, never to be repeated, that Edward Heath had a sense of humour.  During the 1970 election campaign, Harold Wilson, then Prime Minister, was hit in the face by an egg thrown by a Young Conservative demonstrator.  Asked about the incident, Heath said:

"This was a secret meeting on a tour which nobody is supposed to know about. It means that men – and perhaps women – are walking the streets with eggs in their pockets, just on the off-chance."
