"This could include providing affordable accommodation for some of those Ukrainians who have made London their home after fleeing Ukraine following Putin's invasion," the mayor said.
He also called for the restoration of the Ukraine Family Scheme, which allowed Ukrainians to reunite with close relatives who were granted asylum in the UK.
As Ukrinform reported earlier, UK Foreign Minister David Cameron announced on February 22 the introduction of more than 50 new sanctions against persons and entities that support Russian President Vladimir Putin's illegal war against Ukraine.
A group of international legal experts sent a letter to the official representatives of the Group of Seven, stating that the seizure of frozen Russian assets, including those of Russia’s Central Bank, does not violate international law.
