I don't know if the aide bought the wrong tickets- I suspect not, as first class tickets cannot be claimed on expenses- but the aide definitely did try the whole "do you know who I am?" spiel to avoid having to pay the first class upgrade fee. At no stage did Osborne enter a standard class carriage.
Aides do this all the time, especially private secretaries, the difference this time was that a journalist overheard the conversation.
Osborne only paid the upgrade fee when the guard made it quite clear that he didn't care who he was, that is the fare. Good on the guard. Don't for one second think this upgrade fee was paid willingly.
I wouldn't want to say how I know this, but I didn't get this information from the papers, but it that way.
I am not sure I ever read exactly word for word what the aide said, and fear it could have easily been embellished or exaggerated, just as we saw with the police report on what Andrew Mitchell said. Maybe it wasn't, but who knows? Of course if you have some extra insider knowledge that was never revealed, then I have to accept you might know more - but I still haven't seen any text that shows it word for word.
The issue, like plebgate, is that people will believe the version of events that suits their own view - and that's always dangerous (but such is politics). I prefer to say that I don't know what was said and keep an open mind.
Wasn't it the case that they had standard class tickets and travelled earlier, and presumably standard was full (or much busier) and no longer had seat reservations.
I really don't see an issue with trying to talk someone into giving a free upgrade, as plenty of people do that - from all 'classes'. We're always being told to haggle on things, although the 'don't you know who I am?' bit is always likely to result in the risk of someone saying, 'no, who are you?' or similar.
What's more, if there was any desire to do any work, I can see why a chancellor that isn't exactly popular might struggle to get anything done if standing up around a lot of people who aren't exactly his number one fans.
As much as you might imagine him saying he wouldn't dare mix with people in standard (although having standard tickets sort of contradicts that), it seems just as many people would look at him and tell him to bugger off into first class with the other toffs...
