As stated prior in this thread, which you can probably recall, I asked why on earth wouldn't they appear in front of a camera at their secure locations to extend their gratitude to the British state and those who are employed by it in various capacities (NHS, police, etc) for saving their lives and protecting them. It would also afford them the opportunity direct from their own mouths to endorse what May, Johnson and numerous others have claimed and with it slam the Russian state for attempting to murder them. The fact they they haven't suggests no amount of pleading by UK authorities have persuaded them to thus far would only make sense to those who wish to remain in wilful denial of the true circumstances. That includes you, Cyril.
