From the BBC:
UK Prime Minister Boris Johnson begins outlining the latest sanctions against Russia, saying Ukrainians are offering a "fierce defence" and calling Vladimir Putin a "bloodstained aggressor".
He announces that all major Russian banks will face a full UK asset freeze.
The prime minister also promises legislation next week to stop large Russian companies raising finance/debt on UK markets.
Boris Johnson says there will be limits on the amount Russians can deposit in UK banks, with asset freezes extended to around 100 more people.
Airline Aeroflot will be banned from the UK, he says, while there will be "stringent export controls" for technology sold to Russia.
Similar measures will be imposed on Belarus, the PM says.
"Oligarchs in London will have nowhere to hide," he adds.
The UK will work with allies to target Russian finances, Boris Johnson tells the House of Commons.
Russia's shares are falling fast, with the rouble plummeting to record lows against the dollar, he says.
The PM then promises to counter "the Kremlins blizzard of lies and disinformation".
Nato's defences must be strengthened and the leaders of member nations will meet on Friday, he adds.
