Yes, thank you heath480 for the factual information. I already knew that patients are treated individually and according to their need, but it’s useful for it to be pointed out from someone who knows this absolutely.
I did see that Boris was admitted to hospital via a back door and obviously most patients aren’t. However this was very obviously to protect his confidentiality; at the front there would have been press waiting to photograph him. That is probably why he went to hospital in a car rather than an ambulance, as an ambulance outside number 10 would have caused speculation and been much less private for him. The public were kept informed via press releases, the PM deserved to have his confidentiality protected just as much as anyone else.
