Over months of filming and 60 on-camera interviews for the ABC’s landmark political docuseries Nemesis, the free character assessments between former Coalition colleagues fly thick and fast. But as well as the blue language and invective, there are also moments of remorse and regret.

Watch the first episode of the ABC’s political docuseries Nemesis on Monday at 8pm on ABC TV and iview.

Some choice quotes:

What [Barnaby Joyce] says next, referring to Turnbull, stuns me. Let’s just say it’s a four-letter word, connected to another four-letter word.

In one interview, Turnbull is called a “turd” by one of his former supporters.

For his part, the former prime minister recounts being told to “f*** off” by his predecessor Tony Abbott.

The last Coalition prime minister Scott Morrison is labelled “smug” and an “arrogant arsehole” during an interview with one of his former backbenchers.
