Yulia Skripal, the poisoned daughter of Russian ex-spy Sergei, has been discharged from hospital.
The 33-year-old left Salisbury District Hospital on Monday and has been taken to a secure location.
The hospital said: "This is not the end of her treatment but marks a significant milestone."
Her 66-year-old father remains in hospital and is "recovering more slowly than Yulia".
The pair were taken to hospital on 4 March after being exposed to the toxic nerve agent Novichok.
Medical director Dr Christine Blanshard said: "Although he's recovering more slowly than Yulia we hope he too will be able to leave hospital in due course."
The UK government says Russia was behind the poisoning, and Prime Minister Theresa May said Moscow was "culpable" for attack.
But the Russian government denied any involvement and has accused the British of inventing a "fake story".
