Brexit Turmoil Leaves EU Struggling to Calibrate U.K. Outlook

With 50 days to go until Britain leaves the EU and still no clarity on future trading arrangements with the bloc, European Commission forecasters have joined the ranks of economists left unable to make sensible projections even for this year.
