Countries unite against Russian oil: UK PM

"(There was agreement on) the need to move beyond dependence on Russian oil and gas as we go forward, even though it's incredibly difficult for some European countries... What we're doing is making the first step," Johnson said after meeting leaders from the Czech Republic, Hungary, Poland and Slovakia.

"This is a big step that the world is taking... The level of disgust and outrage at what is happening in Ukraine is mounting around the world and the noose is tightening on the (Russian President Vladimir) Putin regime."
