There was an interesting election in Winchester (I don't recall the details, I'll see if I can find it on the web - see below). One of the candidates (Gerry Malone) lost by two votes (to Mark Oaten) and demanded not only a re-count but a re-vote. He won his appeal and the vote was re-run.

The outcome? He lost by a huge majority - taken as a sign that the electorate do not like their decisions to be questioned!
