Analysis finds gap of £5,732 or 24% in average annual salaries in UK, prompting calls for more to be done to tackle problem

Women are likely to earn £300,000 less than men over their working lives, according to a new analysis that has sparked fresh calls for more shared parental leave to close the UK’s stubborn gender pay gap.

Before International Women’s Day on Tuesday, figures show a gap of £5,732, or 24%, in average full-time annual salaries between women and men – more than four decades after the Equal Pay Act of 1970 was introduced.
