I have two points. I'm not so sure that it's stated anywhere that that's the case. I do understand that by convention that's the way the Speaker would treat it. On the application of this, I ask the question rhetorically: is there any standing order that deals with political parties not recognized as an official one? I assume there isn't, and if there isn't, it underlines, sometimes, the difficulty of dealing with Standing Orders as one-offs rather than checking comprehensively. That's why I voted against this and wasn't in favour of it as a general practice.
I am confident that no one will be disadvantaged by the practice that is followed, consistent with this.
