The United States and Britain would seek to cut off Russian companies' access to U.S. dollars and British pounds if the Kremlin orders an invasion of Ukraine, British Prime Minister Boris Johnson told the BBC.

"The plan that we are seeing is for something that could be really the biggest war in Europe since 1945 just in terms of sheer scale," Johnson said.
