War of Jennifer's Ear, the infamous Sun front page and Major campaigning on his soap box. And as the picture above illustrates (shamelessly nicked from political betting) the exit polls got the predictions spectacularly wrong.
1992 also marked the terminal decline of the Tory party as divisions, particularly over Europe, wreaked havoc from which they have never recovered. Diehard party members and supporters departed en masse, donations and subscriptions collapsed between 1992 and 1997. Labour's win in 1997 was less to do with Tories switching sides but that they stayed at home instead.
On a personal note, I remember 1992 well. It was the first election I ever stayed up all night to watch - I missed out being able to vote in it by just 2 months. It also marked the beginning of my journey of eurosceptisim, as the next 18 months left their mark on our country in the form of Maastricht and the ERM crisis.
20 years on and still they can't win an election. Couldn't happen to nicer chaps. Bastards.
