If you study history you will come across the phrase ‘Khaki Election'. This means a UK General Election was about the war and its aftermath. Not much else got a look in.

Usually General Elections are not quite like that. Of course there may be a dominant narrative which most people plug into – the Winter of Discontent in 1979 and collapsing public services in 1997, are two recent examples. But usually key areas of policy such as health, crime, schools and the economy get vigorously debated. More ‘niche' issues like cancer care, the environment, sports and arts policy also get their moment in the sun.
