@Walter Hinteler,
Speaking in the European Parliament today, Jean-Claude Juncker said re-opening the withdrawal agreement "will not happen".
He said the best the prime minister could hope for was "further clarity and further interpretations without reopening the withdrawal agreement" when she meets EU leaders. (May has arrived on the continent, will meet the German chancellor and the Dutch PM today.)
Meanwhile, in the UK, Corbyn - alongside representatives of the SNP, Liberal Democrats, Plaid Cymru and the Green Party - has accused the May of contempt of parliament for "unilaterally" scrapping the planned vote because the government "fear they cannot command a majority".
