Putin threat of biological attack on UK streets: Novichok poisonings in Salisbury were 'wake-up call'

The Novichok poisonings in Salisbury were a “wake-up call” to the threat from Vladimir Putin’s Russia of a chemical or biological attack on Britain’s streets, says Defence Secretary John Healey.

Former Russian double-agent Sergei Skripal, then 66, and his 33-year-old daughter Yulia were left critically ill after the Novichok attack on them in March 2018.
