Workers’ rights and protections for women could be under threat after Boris Johnson added a range of changes to the withdrawal agreement bill following the December general election, the Labour leadership contender Lisa Nandy has claimed.

The MP for Wigan said a series of answers to parliamentary questions that she tabled showed key protections embedded in European court of justice case law could be ignored by the government.

They include provisions for pregnant women, equal pay for men and women, and holiday pay.

Nandy said: “It is absolutely disgraceful that Boris Johnson wants to cast new doubt on rights for women at work that we have taken for granted for decades.
