P&O bosses have been warned to pay their workers the minimum wage or be blocked from docking at British ports.
Transport Secretary Grant Shapps said he was ready to introduce a “package of measures” to “block” P&O Ferries’ plan to replace 800 seafarers with agency workers.
Shapps said he also backed demands for P&O chief executive, Peter Hebblethwaite, to resign and be prevented from being a company director after he admitted breaking employment law by sacking crews on the spot with no notice on March 17.
