Campbell Newman likes to put himself about as a friend of business, a champion of free enterprise. But Mr Premier, you are no friend of the markets.

Drugs war's over, Can Do. Regulation, prohibition, big government? They lost. We lost. And now it’s time to rebuild, by which I mean, it’s time to ching-ching-ching cash in.
