If you didn't read Peter Martin's follow-up on the capital markets ignorance of shadow assistant treasurer Andrew Leigh, you must. It's the best thing we've read in The Age since the Symes family ran the joint!

Still refusing to accept that he completely stuffed up his original op ed – in which Leigh claimed corporate Australia was controlled by five shadowy stockbroking desks – by confusing custodial and beneficial shareholders, the Labor frontbencher told Martin that "the ability of institutional investors to influence corporate decision-making, including the five in this article, is far from clear". But the five – HSBC, JPMorgan, National Nominees, Citicorp and BNP Paribas – aren't institutional investors. Is he still claiming that HSBC owns 33 per cent of Caltex?
