THE referendum on Britain’s membership of the EU will be an “era-defining moment” for workers’ rights in Britain, Jeremy Corbyn will say today.

The Labour leader, who has previously been a fierce critic of EU austerity policies, is planning to highlight new research by the party revealing how many workers benefit from EU employment law.

It shows that 26 million people are entitled to paid holidays through the working time directive, while over 10 million have benefited from rights for part-time, agency and temporary workers and 340,000 women a year benefit from maternity leave.
