Paul is a paid official of the Manx Government, who negotiates with teams and individual riders, and does much of the organisational stuff the Isle of Man is responsible for. Paul was appointed on the strength of his lifelong love of road racing, his extensive contacts, and his knowledge of the practicalities of organising a huge event such as the TT.
He doesn't dictate what happens, but passes on the decisions and opinions of the MMCC, ACU, Manx Government etc, when asked by the public. Don't shoot the messenger.
If you would like to clarify or modify what I have said, Paul, please do as you will obviously be more accurate than me.
