With the questions for Mr Ellis at an end, the inquiry closes its doors for today.
We're back tomorrow morning for more from the Senate chamber, with Andrew Crawford, the ex-special adviser to the former DETI minister Arlene Foster, due to give evidence.
His witness statement is already available on the inquiry's website, so there's some bedtime reading for you.
It promises to be an intriguing day, so join us then and we'll keep you across the details.
Goodnight for now!
