Simon Heffer is someone I have a lot of time for. A fan of Nigel Farage, he is one of the few consistent right-wing commentators who doesn't ignore the existence of UKIP and doesn't blindly support the Tory Party machine.
He has once again in The Telegraph highlighted the damage that UKIP can do to a barely conservative Conservative Party led by David Cameron. Eurosceptic swathes of voters around the country may rebel against the Party they have always voted for, and vote UKIP. This could hugely damage David Cameron's chances of a majority in the next Parliament.
But the simple fact remains that UKIP's core target constituencies - aside from Buckingham - are Labour strongholds. The myth that UKIP is the Thatcherite militant wing of the Conservative Party is doing the Party a huge disservice. Bootle, Hartlepool, Newcastle Under-Lyme, these are the places where the Party is gathering Councillors and momentum.
UKIP is building support up and down the country from ex-members and voters of all of the three main parties, and from those who never previously voted. It is not a small fringe splinter group like the BNP and the Green Party. While David Cameron should fear the rise of UKIP, so should Gordon Brown and Nick Clegg.
