The warnings came as a Reuters poll warned there was a 25% chance of a no-deal Brexit. The Green Budget, published by the Institute for Fiscal Studies, today also predicted a £100 billion hit to growth over the next three years in a cliff-edge scenario. Citi chief economist Christian Schulz, writing for the IFS, said: “We would expect to slash our UK GDP growth forecast by around five percentage points over two to three years in case of a ‘no deal’.” Manufacturers, financial services and transport — accounting for 10 million jobs and a third of the economy — are worse affected.
