Green leader Zack Polanski must "step up and lead" over the growing row about the party's "Zionism is racism" policy, one of his party's MPs has said. The Greens' Westminster leader Ellie Chowns MP told Sky News she believes the policy, which was voted through by members earlier this month, "has been damaging". Labour have said they will end power-sharing arrangements with the Green Party on local councils where those local Green groups fail to condemn the motion. Labour say the 19 councils where they share power with the Green Party of England and Wales have seven days to respond before existing agreements are ended. The Green Party has called Labour's ultimatum "undemocratic". Ali Fortescue is joined by Green MP Ellie Chowns, ex-Labour MP Caroline Flint and the founder of ConservativeHome, Tim Montgomerie, to debate the motion.
