I go back again.
If it was not you, you have not gone through any of the research or any of the documents that you've asked for and been given. Everyone is pointing the finger at you, saying you're the one who made the decision. Your quote is that it was only a “technical direction”, yet nobody in all the testimony that we're hearing is taking responsibility for what happened.
Who is going to take responsibility here? Do you take any responsibility for what happened here?
You haven't provided the name of the person through all the documentation notes you have been given and been going through. You haven't pinpointed how tens of millions of dollars of sole-sourced contracts got awarded over multiple years. The whole starting point is that you're not sure who it was, and it doesn't really matter to you.
If it wasn't you, do you accept responsibility, and if you don't, who should?
