The fall-out from the UK's awarding of post-Brexit ferry contracts has continued with news that P&O Ferries is suing the government.

The UK operator is objecting to a pay-out of £33m ($44m) to rival Eurotunnel to settle a court case against the UK state.

This legal battle was prompted by transport minister Chris Grayling awarding deals worth more than £100m to DFDS, Brittany Ferries and Seaborne Freight to provide vessels on routes other than Dover to Calais, to prevent congestion after a potential no-deal Brexit.
