The photos were in the online version of a couple of local papers, and I noted they had a watermark of some kind on them - presumably related to the photographer or photo agency, so in this instance, I don't think we can blame the DM for taking them. It wasn't a secret that Andy was going to see specialists, so IMO it's not that big a deal that he was photographed in the car-park. It's not like he was snapped outside the STD clinic!
The local paper gave the name of the hospital, presumably quite proud that Andy was going there for advice, so I don't think there was any malice intended, although it is without doubt an invasion. I think it's nice that it shows that NHS specialists are considered amongst the best (even if it were a private consultation, it's the same staff), and that they exist outside of London.
They were first published before Andy made the statement about withdrawing from the FO, but I completely agree with the notion that the text surrounding them is entirely speculative and made up to suit whichever angle they are running, and trying to make out they've done proper journalism.
I can't see anyone believing that the photos captured the "moment" Andy was told ... Most likely, a couple of them went into his consultation with him (physio and fitness trainer as they speak the right language and have good knowledge of what treatments and exercises he's already done) and the rest of his team were all there so they could discuss what the specialist said while it was still fresh in their minds, and know what they are up to. From the look on Dani's face, I think he was in charge of telling Ivan!
It's not normal for a consultant to walk their patients to the car, but it looks like an out-patient clinic, not part of the main hospital building, so it's probably just a couple of hundred metres from his office to the car-park, and if he didn't have an appointment immediately afterwards, why not? He may have been going to his car anyway, or to the main building and just fancied the opportunity for a chat on the way out. Who can blame him? I'm sure we'd do the same!
