Yulia Skripal is no longer in a critical condition and is “improving rapidly” following a nerve agent attack in Salisbury, Independent reported.

Doctors said her father, Sergei Skripal, remains in a critical but stable condition as the police investigation into the attempted assassination continues to widen.

Ms Skripal is said to be conscious and talking, raising the possibility that she will be able to talk to counter-terrorism detectives about the incident on 4 March.
