THIS is promoted as the most interesting and unpredictable general election in British history.

Who will win, or what coalition will be cobbled together after May 7, is still uncertain. So far it has failed to raise real excitement.

The Conservative slogan about sticking with their ‘long-term economic plan’ scarcely grabs the attention like Harold MacMillan’s 1959 winning ‘You’ve never had it so good’.

Labour’s ‘Better Plan for a Better Future’ does not match up to Tony Blair’s 1997 ‘Things Can Only Get Better’ let alone Harold Wilson’s 1963 promise to forge a new Britain in ‘the white heat of technology’.

Nick Clegg’s pledge the LibDems would provide a ‘heart’ for a Tory administration and a ‘head’ for a Labour one is catchier, but code for wanting to be part of the next coalition whoever is in charge.

All three of the UK’s traditional ‘main’ parties are playing it too safe so the minor players are having a field day. SNP leader Nicola Sturgeon’s is heroine of the moment and UKIP’s Nigel Farage just has to take South Thanet to be a populist icon.

While David Cameron sidesteps dangerous TV confrontations and Ed Miliband neutralises his ‘geeky’ image by being self-consciously statesmanlike, the ‘Wow’ factor is missing.

This campaign is crying out for one of them to take a political risk. That might break the opinion poll logjam, energise the campaign, and shape the result.
