If Sergei and Yulia Skripal survive being poisoned by Novichok nerve agent, they may be left suffering illnesses that ruin their lives – which may be the point of the attack, security experts have warned.

Andrei Zheleznyakov was said to have been injected with an antidote almost immediately, but a friend said he still went from being a jovial, creative man to suffering “chronic weakness, toxic hepatitis, epilepsy, severe depression and an inability to concentrate”, before dying five years later.
