FAIRFAX Media’s share price rallied yesterday as the market focused on possible break-up moves flowing from John Singleton and Mark Carnegie’s decision to join forces with Gina Rinehart to agitate for change at the publishing and broadcasting company. Advertising baron Mr Singleton and investment banker Mr Carnegie’s investment vehicle Gutenberg Investments yesterday revealed it had bought 3.5 million shares or 0.152 per cent of Fairfax Media through a substantial shareholder notice required by their alliance with 14.99 per cent shareholder Gina Rinehart.
