The sanctioned individuals include Vadim Konstantinovich Kalinin, who oversaw the brutal prison camp where Mr Navalny was kept in solitary confinement for up to 2 weeks at a time. Mr Navalny’s condition had deteriorated in his 3 years in prison. Mr Navalny suffered from being denied medical treatment, as well as having to walk in –32C weather while being held in the prison.

The UK is the first country to impose sanctions in response to the death of Mr Navalny, a political prisoner who dedicated his life to exposing the corruption of the Russian system, calling for free and open politics, and holding the Kremlin to account.
