Why refer to her cousin (Victoria) as murderous, what has Victoria done
Nothing, as far as I know. Just displeased the handlers of this case in the UK. It was sarcasm.
Perhaps the medical staff hadn't told the bbc and other media the change in circumstances, if the bbc new they would have reported it.
I don't doubt they failed to inform, and also that the BBC and others are failing to ask daily for updates, and very submissively going along with whatever the authorities feed them, as and when they choose to feed them. Which ended up looking embarrassing when it was Yulia, through the phone call, who broke news that the authorities hadn't yet broken.
Perhaps she just isn't ready to appear in front of the media. It is certainly not proof of anything what so ever
There's not even a need for her to make a media appearance, just a pressing need, whether it's legal or not, for her to take two minutes to speak to a representative of the Russian embassy.
