Sergei Skripal is no longer in critical condition and "improving rapidly" after collapsing from nerve agent poisoning last month.
Dr Christine Blanshard, Medical Director at Salisbury District Hospital said in a statement:
"Last Thursday, I informed you that Yulia Skripal's condition had improved to stable. As Yulia herself says, her strength is growing daily and she can look forward to the day when she is well enough to leave the hospital.
"Any speculation on when that date will be is just that - speculation. In the meantime, Yulia has asked for privacy while she continues to get better - something I'd like to urge the media to respect.
"I also want to update you on the condition of her father, Sergei Skripal. He is responding well to treatment, improving rapidly and is no longer in a critical condition.
"As you'll appreciate, I won't be giving any further updates at this time."
