Foreign Secretary Liz Truss has said Britain is "ready" to unleash tough sanctions against Russia's elite if Vladimir continues to threaten Ukraine with aggression.
Ms Truss said the "the ball is firmly in Russia's court" and if they do not stand down, anyone sharing responsibility for the Kremlin's "aggression" will have their assets frozen in the UK.
But David Lammy, Shadow Foreign Secretary and Tory backbenchers said the measures do not go far enough.
