Headline advisory director Andrew Carswell has laid bare the "toll" Anthony Albanese’s "brutal assassination" of Scott Morrisons character took on the former prime minister.

Former prime minister Scott Morrison has revealed he received treatment for debilitating anxiety during his time in office.

“What was laid out by the Albanese opposition was a brutal character assassination of a sitting prime minister,” Mr Carswell told Sky News Australia host Sharri Markson.

“Of course it is going to have a toll.

" Of course the relentless war against Scott Morrison’s character was going to have a toll.

“It was hard to know sitting there what was said about Scott in public, was not the Scott that you knew in private.”
