Yulia Skripal has said her strength is "growing daily" after the nerve agent attack which left her and her father in intensive care.
Her first public comments since the March 4 attack were released shortly after Russian TV reported that she had contacted a relative in Moscow to say she and Sergei Skripal were recovering and that she would soon be discharged from hospital.
In her first statement since coming out of a coma, released by the Metropolitan Police, Yulia Skripal, 33, said: "I woke up over a week ago now and am glad to say my strength is growing daily. I am grateful for the interest in me and for the many messages of goodwill that I have received."
Ms Skripal thanked healthcare workers at Salisbury District Hospital as well as "the people of Salisbury that came to my aid when my father and I were incapacitated".
Russia has appealed for the UK to issue visas for relatives to visit the Skripals in hospital in Salisbury, where they are being treated for exposure to nerve agent Novichok.
Moscow has called a meeting of the United Nations Security Council to discuss the incident, with foreign minister Sergey Lavrov saying the UK has "legitimate questions" to answer about what happened.
But security minister Ben Wallace said it was "beyond reasonable doubt" that Russia was to blame for the attack, as the UK sought to maintain diplomatic pressure over the incident.
Ms Skripal's statement was released as Russia’s ambassador to London, Alexander Yakovenko, repeated Moscow's denial of responsibility for the attack.
Foreign secretary Boris Johnson's claim that Russia maintained a stockpile of Novichok "likely for assassination" was "untrue... not supported by any evidence ... unacceptable", he said.
