Exclusive: Buttrose mounts robust defence of broadcaster’s independence in response to questions about Four Corners’ episode Inside the Canberra Bubble

The ABC chair, Ita Buttrose, has accused the government of a pattern of behaviour which “smacks of political interference” in a robust defence of the public broadcaster’s independence, according to a draft of a letter responding to a barrage of Coalition complaints about the Four Corners program Inside the Canberra Bubble.

In the program broadcast last month, the journalists Louise Milligan and Lucy Carter investigated complaints about attorney general Christian Porter, including an alleged history of sexist and inappropriate behaviour towards women, and an affair the acting immigration minister, Alan Tudge, had with a female adviser in 2017.
