Novichok nerve agent use in Salisbury: UK government response

Also published by:
10 Downing Street

This page sets out the government's response to the Salisbury incident, where a military-grade nerve agent was deployed in the UK on 4 March 2018.

On Sunday 4 March Sergei and Yulia Skripal were poisoned with a military-grade nerve agent of a type developed by Russia.

Latest update

Prime Minister Theresa May gave a statement to Parliament on 14 March. Russia has provided no explanation as to how this agent came to be used in the UK, and there is no alternative conclusion other than that the Russian State was culpable for the attempted murder of Mr Skripal and his daughter. This represents an unlawful use of force by the Russian State against the United Kingdom.

The Prime Minister stated that the UK government will:

  • expel 23 Russian diplomats who have been identified as undeclared intelligence officers
  • develop proposals for new legislative powers to harden our defences against Hostile State Activity
  • enhance our efforts to monitor and track the intentions of those travelling to the UK who could be engaged in activity that threatens the security of the UK and of our allies
