The full-time pay gap in the United Kingdom is 14.1% and if you factor in part-time work, the vast majority of which is done by women, it leaps to a shocking 18.4%.
The data was released to mark Equal Pay Day, the day of the year on which women begin working "for free" relative to the amount men earn for the same job.
The pay gap has stood at 14.1% since 2015, meaning it would not reach 0% until 2117 if it continued to close at the same rate as over the past five years, it said. She also called for the Government to introduce mandatory shared parental leave to prevent women from taking on the bulk of the childcare responsibilities and thus losing out on their professional development.
A charity warns the pay gap is widening for some women, fearing it could take a century to correct the imbalance.

Working women in Britain face a 100 year wait to be paid the same as men, with progress towards closing the gender pay gap stalling as younger women's wages lag behind, a women's rights group said on Friday. "During that time the gender pay gap has reduced, but it has not reduced enough".
It's everywhere. The 14.1% mean pay gap is a national average - it's actually much worse in some areas.
In the North East it's growing, up from 8.7% to 10.2%. There is a huge generational gap included in this, as the gap for women in their 30s (6.7%) is vastly smaller than for women in their 40s (17.1%).
The society found the gulf widening for younger women under a different, average measure reported by the ONS.

Another worrying feature of this year's data is the number of women who are earning below the minimum wage. Brazilian footballer Neymar's salary is just as uncharacteristic of a normal man's pay pack as it is of a woman's.
Under new government rules, all companies with more than 250 employees will have to report their gender pay gaps by April 2018.
With all the intelligence we have in the world, the gender pay gap is a solvable - and should be a solved - problem.
What Can Be Done?
It's Equal Pay day so, obviously, everyone is talking about the gender pay gap.
The Fawcett Society said younger women as well as older female employees were now seeing their pay fall behind that of men, claiming that the drive to equalise pay is "going backwards".
She says employers often say they "respect" women, and champion specific examples of women who are doing well in their organisations but are are "not looking holistically" - at how they are treating all their female employees.
Nicky Morgan, Conservative MP said "We've seen the best employers make ground breaking strides in tackling gender inequality".
Mackay explained that typically women are less likely to invest than men, sticking to cash because of "mistrust, a greater fear of investment risk and the time pressures of day to day life".
