I might ask Mr. Swales to add to my answer.
The 2012 audit did focus on the purchasing of the fighter jets. The 2018 audit did not.
In the 2018 audit, we were looking at the readiness or the ability of the forces to meet the NORAD and NATO requirements, but in 2012 our scope was a bit different. I know that there were concerns about management, about the assessment of risks and about costing, but Mr. Swales might be able to add to that.
