Among the other Russian oligarchs targeted by the UK are Mikhail Fridman and German Khan, co-founders of the powerful Alfa-Group, and Pyotr Aven, the head of the Alfa Bank.
Between them have a combined estimated worth of more than £100 billion.
The UK has also taken action against a number of Putin’s political allies, including Prime Minister Mikhail Mishustin, Sergei Shoigu, the defence minister, and Dmitry Medvedev, the former president of Russia.
Alongside Peskov, other propagandists to be targeted include Maria Zakharova, the Russian foreign affairs spokesman, and the notorious internet “troll farm”, the Internet Research Agency, which was said to have interfered in the US presidential election.
Dmitry Peskov, who has long been accused of corruption, was hit by US sanctions last week and was added to the UK list as part of the latest crackdown aimed at tightening the screw on Moscow.
His second wife, Tatiana Navka, the Olympic ice dancer, and his daughter, Elizaveta Peskova, who is a social media influencer, have also been hit by the latest round of sanctions and have had their assets frozen.
