Former Russian agent Mr Skripal’s wife, son and older brother have all died in the past two years. The woman found slumped on a shopping center bench alongside a former Russian agent convicted of spying for Britain is his daughter.
Yulia Skripal, in her 30s, and father Sergei, 66, are critically ill in hospital after being found unconscious in Salisbury, Wiltshire.
Sergei Skripal was convicted of passing the identities of Russian intelligence agents working undercover in Europe to the UK’s Secret Intelligence Service, MI6.
In July 2010, he was one of four prisoners released by Moscow in exchange for 10 Russian spies arrested by the FBI as part of a swap. He was later flown to the UK.
