7. Russia responds

As the inquiry prepares to move from Salisbury to London, Andy Howard and Marie Lennon review a momentous week of evidence, which saw the emergency services interrogated and the communication between them questioned.

Dawn's family ask for President Putin to appear at the inquiry in person to answer questions about her death and the Russian Ambassador to the UK gives his response.

Focus turns to the protection given to Sergei Skripal; should he have been living in the UK under his own name without surveillance?

This episode was made by Marie Lennon, Andy Howard, Tom Ryan & Dan O’Brien.

Executive production by Mary Sanders and Naomi Wordley.
