Jeremy Corbyn's Russia problem just got worse.
Long at the far left of British politics, the Opposition Leader misjudged the mood of MPs - including from his own Labour Party - by casting doubt on Russian Government involvement in the poisoning of a former spy on UK soil.
Prime Minister Theresa May listed a slew of measures the UK will take against Russia for the attack more than a week ago in western England, including the expulsion of 23 diplomats. Sergei Skripal and his daughter, she said, were poisoned by a nerve agent developed by Russia.
Corbyn then stood up to "echo" her words of support for emergency services - but noticeably failed to back her condemnation of Russia.
He suggested nothing was yet proven, and asked May if it was possible that Russia lost control of the nerve agent rather than deploying it itself.
