Don't worry about Angus Campbell, he's a philosopher and a leader who will be stronger for what's happened.
However I think it was a mistake for Morrison to make him the public face of Operation Sovereign Borders and put him in the position of taking press conferences where his replies are so often "No Comment". Minister Morrison should be between the public and Campbell.
For those with 50 minutes to spare I highly recommend Angus Campbell in Conversation with John Bertrand at the following link
