ABC at centre of political storm

There is chaos at the top level of Australia's public broadcaster the ABC after leaked emails revealed its chairman tried to get a senior journalist sacked because the government didn't like what she was reporting. Communications Minister Mitch Fifield has launched an inquiry, saying it's important the public have confidence in the ABC's independence. The broadcaster's staff have passed a unanimous vote calling on chairman Justin Milne to step aside while the matter is investigated. But he's refusing to go anywhere. Susie Ferguson talks to Michelle Grattan, chief political correspondent for The Conversation.
