CLEVELAND Police is the only force in the country with a zero per cent gender pay gap, figures show.

The force with the highest median gender pay gap is Derbyshire Constabulary at 28.8%. Durham Constabulary has the fourth highest at 27%.

No police force has a gender pay gap in favour of women.

Everyone Matters Chief Inspector Kathy Prudom, said: "Cleveland Police is dedicated to being a diverse and fair organisation. Recent figures around the gender pay gap are encouraging, however equality is more than just a number, it is an entire way of working and behaving. Our Everyone Matters programme is working towards this true equality and inclusion for all."

Every police force in England and Wales has submitted its figures to the Government Equalities Office, something all companies and public bodies with 250 employees or more must do.

The gender pay gap is calculated as the difference between the average salaries of men and women - it is not the same as equal pay, where firms are required to pay people doing the same job the same salary regardless of gender.

The national median gender pay gap is 18.4% - 23 police forces have a pay gap at or below the national average, while 21 are higher.
