Mr. Tony O'Brien:

I would not say it was the one and only occasion on which I was invited. I receive invitations to speak at hundreds of conferences, most of which I decline. However, I accepted this one. We already discussed it. The issue is whether I should have allowed the company to pay for the travel. I will reflect on the question. I cannot undo what was done. My decision to allow it to pay was motivated solely by the fact that it would save the organisation from paying.
