The implications for this crisis go well beyond Ukraine. Putin has effectively said that the protection of ethnic Russians in another country is not a matter for the laws of that country or the constitution or the Government, but for an external power—namely Russia. This is a fundamental challenge to international law. Does my right hon. Friend agree that it is not enough just to de-escalate on Ukraine; we need assurances from the Kremlin that Russia will not interfere in any other sovereign state simply on the basis that ethnic Russians live there? Otherwise, sanctions must continue on that very basis.
