Friends of poisoned Yulia Skripal have claimed she is already dead and accused the Government of covering the news up.
Ms Skripal was exposed to a toxic substance alongside her father and former Russian spy Sergei Skripal in Salisbury earlier this month.
The British Government has said the pair are still fighting for their lives in hospital.
But Yula Ni, who is listed as one of 33-year-old Ms Skripal’s friends on VK, a Russian social networking site, has claimed she may already be dead.
Sergei Skripal and his daughter Yulia (pictured in Zizzi in 2016) left a trail of nerve agent in the restaurant after their poisoning
She told The Telegraph: ‘I need some undeniable proof that she is actually alive, because we have suspicions that the truth about Yulia’s and her father’s conditions are being held from us.
‘It appears to be very strange that there is not more concrete information available. The week has passed since they went into a comatose state.
‘Can they breathe on their own or are they on a respirator? Do they react to light or have any other basic reflexes? The authorities should have already released some information to the public!’
Ms Ni, who has known Ms Skripal for decades, questioned why British police had not made more information available.
Another childhood friend of Ms Skripal, Irina Petrova, also cast doubt over whether she was still alive.
She said in Moscow most of the streets are covered by CCTV and she found it strange there was no video of the attack.

And she said the fact her friend lived without fear, posting prolifically on social media about her life, made her doubt whether the Russian Government was behind the attack.
But she admitted Ms Skripal would be unlikely to speak of any threats because she was an ‘ice queen’.
It comes as new footage emerged of Sergei Skripal’s BMW being driven towards the centre of Salisbury on the day the double agent was poisoned.
Both he and his daughter remain in a critical condition in hospital.
