It is inconceivable that sanctions against Russia would be lifted just because of a ceasefire. It would be absolutely unthinkable, said British Prime Minister Boris Johnson, The Independent reported.

The West must make sure none of our friends and partners around the world back down from sanctions, he said, instead calling for action to increase the economic pressure on Putin.

Johnson agreed to calls to send Vladimir Putin to the dustbin of history by warning NATO allies not to backtrack on sanctions on Russia.
