LISTEN: Crown shares plunge after James Packer sells half casino stake by PeterRyan

Shares in the casino company Crown Resorts have dived after billionaire James Packer sold half his stake to a Macau-based competitor for 1-point-8 billion dollars. In the absence of a bidding war, Crown investors have been offloading their shares given that the 13 dollars on offer looks like the best price they might get. ABC's Peter Ryan says there are some big questions remain about how gaming regulators might view the deal given ownership restrictions on Crown's Barangaroo casino project in Sydney.
