Exactly what I was thinking.
There is no way this could be acceptable in the public sector. Yes Tony Malone could speak at the conference and have reasonable expenses and accommodation covered by the organiser but this is taking the mickey.
It should have had to have been declared as part of the entire trip. In reality he would be duty bound to decline this as it is of inappropriate value.
Investigation needed there as well. What is acceptable in the private sector is not in the public sector.
Heck, if a supplier even wants to take us out for a meal there are strict guidelines on what is acceptable.
