Cancompany rules over ride the ANO? No.
I did say that as far as I can find, and I am willing to be contradicted that is the legislation that applies. It means unless there is something else that applies there is no way of carring a loaded firearm on an aircraft. However, as I said at the end the ANO is not an act of parliament, its a Stautory instrument, it means its passed by the Privvey Council, as I recall that means that a group of Privvey councilers stand round The Queen and she agrees there and then to enact the instrument. In other words if what I quoted before is correct, then it can be changed in minutes.
You know as well as I do that President Tony flies British, his security arrangements are not something I can comment on, afterall you are a forigen national.
