The pending strike at the UK’s biggest container port will divert ships and disrupt more than $800m in trade, analysis shows.

Industrial action by more than 1,900 workers is expected to bring the port of Felixstowe in eastern England to a standstill between Sunday 21 August and Monday 29 August.

Container shipments will be shifted to larger European ports, including Rotterdam, Hamburg and Wilhelmshaven, according to the analysis by Alps Marine, part of Russell Group, a data and analytics company.
