Britain's Sunday Times newspaper has reported that a former Russian spy and his daughter, who were poisoned with the deadly nerve agent Novichok, are now living in New Zealand.
Sergei and Yulia Skripal were found unconscious on a park bench in the English city of Salisbury two years ago.
They recovered and lived in a safe house for a year, before being sent overseas with new identities.
Russia denied Britain's accusation of attempted murder.
British woman Dawn Sturgess later died after spraying her wrist with the contents of a perfume bottle containing Novichok, believed to have been discarded by the poisoners.
