Has Labour actually got any policies that are radically different? They seem awfully cautious given the open goal they've got at the moment? I suspect the truth is that neither party wants to incur the wrath of the hidden power base of the country...the financial markets. Look at how quickly they disposed of the Pork Marketeer and her balmy financial policy....wilted faster than a lettuce! The only time in my voting memory that I can recall someone significantly altering the dial was when Blair steered Labour to the middle ground. And there they remain despite the efforts of Corbyn et al. With everyone fighting for the middle, there's no room left which may explain why Farage has decided to exhume himself and lay claim to the right wing (which cuts across the social divide).
Being as I love spitfires but hate warm beer, I guess I'm one of Wittons 20 percenters!
