THE UK Government has sanctioned more than 300 Russian parliamentarians as ministers sought to “tighten the screw” on Moscow over the invasion of Ukraine.

Foreign Secretary Liz Truss said 386 members of the Duma – the lower house of the Russian parliament – are being banned from travelling to the UK and any assets they have in the country will be frozen.

The Government originally announced its intention to sanction the parliamentarians last month over their support for the the Ukrainian breakaway regions of Luhansk and Donetsk.

The move follows the announcement on Thursday that seven more oligarchs linked to Vladimir Putin – including Chelsea owner Roman Abramovich – were being subjected to similar measures.

In a statement, Truss said: “We’re targeting those complicit in Putin’s illegal invasion of Ukraine and those who support this barbaric war. We will not let up the pressure and will continue to tighten the screw on the Russian economy through sanctions.

“Together with our allies, we stand firmly beside our Ukrainian friends. We will continue to support Ukraine with humanitarian aid, defensive weapons and diplomatic work to isolate Russia internationally.”

Downing Street declined to say whether any of the 386 sanctioned members of the Russian Duma have any assets in the UK.

A spokesman for the Prime Minister said: “The measures we put in place will ensure that any assets they do have in the UK will be frozen and they will no longer be able to travel to the UK or do any business here, but I wouldn’t go through the details of individuals.”
