[Sun] Skripal, 66, and Yulia, 33, are critically ill in hospital, with counter-terror officers having taken charge of the inquiry.They are investigating a theory that a Kremlin assassin may have been responsible. Yesterday it emerged that the ex-spy's wife and son have recently died in mysterious circumstances.
His wife Lyudmila died at the age of 59 in 2012, before his son Alexandr, last year, died at the age of 43.
While Lyudmila's death certificate reads that she died of cancer, neighbours claim she actually died in a car crash. There have been conflicting reports about how she died.
