History of women's fight for equal pay
Businesses with more than 250 employees will have to provide details of how much they pay men and women, the government has said.
These statistics will then be compiled in a league table, in an attempt to tackle the UK's gender pay gap.
The BBC's Victoria Derbyshire programme looks back at how the issue has progressed in recent times.
The Victoria Derbyshire programme is broadcast on weekdays between 09:15 and 11:00 on BBC Two and the BBC News channel.
