New sanctions target six figures involved in the trial of Vladimir Kara-Murza, who is facing 25 years in a penal colony after the rejection of his appeal, UK Foreign Office said in a statement Monday.

The statement added UK government has sanctioned six individuals for their involvement in the politically motivated conviction of Vladimir Kara-Murza.

"The sanctions included three judges, two prosecutors and an 'expert witness' have been sanctioned for their part in his politically motivated targeting.

Kara-Murza, a dual British national, is being persecuted by the Russian regime for his anti-war stance." It comes as the Foreign Secretary calls for the immediate release of Mr Kara-Murza, who is facing 25 years in prison after his appeal against trumped up charges was rejected in Moscow today.

Kara-Murza is an opposition politician, journalist, and human rights activist in Russia.

He has received wide recognition for his work, including the Vaclav Havel Human Rights Prize.

The charges against the dual British-Russian national included treason and spreading 'knowingly false information' about the Russian armed forces.
