Ministers should trigger immediate "criminal action" against P&O Ferries after the company sacked 800 staff without warning or consultation, Labour has said.
Shadow transport secretary Louise Haigh told the Commons the government can act straightaway and bring legal action under the Trade Union Act against the Dubai-based firm.
The Government has given the company a deadline of 5pm on Tuesday to explain its shocking decision last Thursday to fire all 800 British workers by video message and without consulting unions.
