Operation Yellowhammer: ‘Just in time’ supply chain at risk, warns chemicals sector

Crashing out of the EU without a deal could cause months of supply chain chaos, according to official contingency plans published yesterday, with the UK chemicals sector urging the government to secure a Brexit deal to prevent disruption.
