Today in Media Files, controversy over the Lowy Institute's speaker for its newly named lecture in memory of broadcaster Mark Colvin, and The Advertiser breached Australian Press Council guidelines with its description of a poll.

Colvin lecture controversy. A Lowy Institute decision to call in a controversial self-described climate "agnostic" as its inaugural speaker for its Mark Colvin Lecture has caused a stir. The Lowy Institute Media award dinner lecture has been named after the late ABC foreign correspondent and PM presenter, who died in May after suffering from a chronic illness contracted while reporting on the Rwandan genocide. The Lowy Institute announced that the lecture this year would be delivered by conservative New York Times columnist Bret Stephens, who writes on foreign affairs but has called climate change one of liberalism's "imaginary enemies".
