On Friday BBC2's lunchtime "Daily Politics" programme discussed Marx. It's 31 minutes in on here:

The "representative" of Marx was Alan Woods, of the Ted Grant section of Militant, who has been an economic adviser to Chavez in Venezuela. Naturally, he wasn't very good, arguing that even though nationalisation wasn't socialism it had allowed Russia and China to develop industrially (that was always the line of this particular Trotskyist sect and why they argued that the old USSR wasn't capitalism but was in fact better than capitalism). But he wasn't as bad as Madsen Pirie of the Adam Smith Institute. Who could be? The discussion only lasted 10-11 minutes but maybe it's a sign of the times that they have to discuss Marx even if only to dismiss him.
