After the event, it all looked pre-ordained; beforehand, too many had been too scarred by past electoral mirages for anyone to take anything for granted. That was what made the election night of 1-2 May 1997 so remarkable. This book is the story of it.
Actually, it's two stories of it, as it records both the historic events themselves - the victories and defeats, the politicians' speeches, the 'new dawn breaking' as Blair puts it - and also the coverage of those events, especially on the TV. That double narrative forms a good framework within which to flit in and out of specific declarations, analyse the results and their significance and provide background to the people involved.
Cathcart writes incisively and with good humour, not underplaying the importance of what's going on but not being overly reverential either - election nights always provide the bizarre and comical alongside the historic and nation-changing. He captures it all with equal relish. There's also an energy driving through the book as the action pulsates around the country and the emotions of ecstatic triumph and resigned horror sweep the various parties.
Nowhere was that more true than at the defining moment of the night and the one that indirectly gave the book its title: in Enfield Southgate, where Michael Portillo, then seen by many - not least himself - as a future Tory leader, lost his supposedly safe seat on a massive swing. On a night of shocks, this was the biggest of the lot. At gone 3am, it was also just about the last one too.
In a way, it's quite a lightweight book; it's certainly very readable. There's not the deep analysis or background information that you'd get in a Kavanagh or Butler guide but that shouldn't distract from the amount of information there is: it's a properly researched book filled through with stats. That, however, is a secondary purpose. The main one is a record of the night itself and it's one it fulfils very well.
