London Mayor Sadiq Khan has hit out at the capital’s “unacceptable” gender pay gap after it was revealed the difference between men and women's pay at some of the city’s largest public bodies is more than 10 per cent.

City Hall has published the gender pay details of all organisations overseen by the Greater London Authority, with Transport for London’s (TFL) pay gap 19.2 per cent and the Metropolitan Police 11.6 per cent.

Women at TfL are paid on average £5 per hour less than men and £2 per hour at the Met.

Mr Khan said: “We still have plenty of work to do to close the gender pay gap across the GLA and I will be working with all functional bodies to do everything we can to promote gender equality.

"It is unacceptable that in London, the most progressive city in the world, that your gender determines how much you get paid and your career prospects.

“Clearly we all need to do much more to put our own houses in order.”

The only GLA body found to not have a gender pay gap was London Fire Brigade, with the Greater London Authority, the Mayor’s Office for Crime and Policing among others all paying women on average less than men.

The London Legacy Development Corporation recorded an average pay gap of just more than £10 – a mammoth 35 per cent difference.

Mr Khan has called for each body to put together an action plan for tackling the pay gap.

Sam Smethers, Chief Executive of women’s rights charity the Fawcett Society, said: “[The mayor] has the power to influence what other employers do and drive home the message that gender pay gap reporting is coming.

“But reporting the gap is the first step. We need to focus on an action plan to close it and we look forward to working with the mayor's team to make this a reality.”

The Met has claimed that there is “little opportunity” for the force to influence the pay gap given that police officers’ pay is set nationally.

It pointed to the fact that its pay gap was lower than the London average of 16.3 per cent.

A spokesman said: “We are not complacent and we have already taken action to reduce the gap by removing long service increments which indirectly have a disproportionate impact on female staff.

“We remain committed to ensuring the Met is fair and inclusive so that our staff can be proud of where they work and we ensure equal opportunity for all.”
