Viktoria Skripal also said she doubted that Britain would give her a visa that would allow her to see her relatives as tensions continue to rise between Russia and the West.
Speaking about the UK authorities, who she claims wanted her to condemn Russia, she said: “While I don’t know the whole situation, they ask me to voice my opinion.
“If they tell me, ‘We’ll return Yulia to you if you say ‘Russia is filth,’ then I’ll stand up and say ‘Russia is filth’ and take Yulia back to that filth.”
Dr Christine Blanshard, medical director of Salisbury District Hospital said Mr Skripal’s condition was raised to stable from critical on Friday, and he “is responding well to treatment, improving rapidly”.
Officials did not say whether or not he had regained consciousness, however.
Russian officials have accused Britain of denying them access to Yulia Skripal.
The British Government said that the choice not to meet with Russian officials was hers.
The British Foreign Office said in a statement released Thursday: “We have conveyed to Ms Skripal the Russian Embassy’s offer of consular assistance.
“Ms Skripal is now able to choose if and when to take up this offer, but to date, she has not done so.”
Viktoria Skripal recorded a ‘brief call’ - as she described it - this week from Yulia Skripal and sent the recording over to Russian state television, who have broadcast the footage repeatedly.
