Are you some kind of socialist?

The business secretary, Vince Cable, told an audience at the Cass Business School yesterday that he was sometimes accused of being " some kind of socialist ". "I am a liberal. I am a free trader. I believe in open markets. Anyone who doubts the clarity and consistency of my views should look up my writing on trade policy from the 70s, attacking protectionism. I think the WTO is a good thing, not a neoliberal conspiracy … Nor do I have a philosophical problem with big business. I spent years working for one – a big, controversial oil company, no less – and I'm proud of the world-class managers and engineers I worked alongside. I do, however, think that the market economy has to deliver opportunity rather than constrain it." Are you "some kind of socialist" – and if so, what kind?
