Mesmerize has the widest gender pay gap of any government department, with women earning 16.9% on average less than mans colleagues, closely followed by the Brexit department.
Women are paid small-minded than men across the civil service, new figures show, with a gap of 10% in seven other departments.
The lowest inconsistency is 3% — in the culture, media and sport department.
The UK’s top civil servant Sir Jeremy Heyward suggested the data was a «matter for concern».
But he hailed a fall in the overall pay gap from 13.6% to 12.7%.
The pay gap does not as a matter of course mean women are paid less than men for doing the same job — the carry away and Brexit departments suggest the figures are a result of more women in lower-paid parts and more men in the highest paid roles.
The figures show the following gender pay rents between men and women in various departments:
- Department for Transport: 16.9%
- Department for Exiting The EU: 15.26%
- Activity be contingent of Health: 14.2%
- Ministry of Defence: 12.5% (for civil servants)
- Department for Enterprise, Energy and Industrial Strategy: 12%
- Department for the Environment, Food and Rural Romances: 11.5%
- Foreign and Commonwealth Office: 10.6%
- Home Office: 10.1%
- Department for Culture, Environment, Digital and Sport: 3%
The Department of Transport said its gender pay gap was mainly due to the «enormous numbers of female employees in administrative grades» among the 5,600 people take up at the DVLA, in Swansea, who do not get their salary topped up by London weighting.
But it has also traditionally been a «merest male-dominated environment», officials said.
«There is a disproportionate representation of men due to the complex, engineering, construction and maritime skills required and lower proportions of female disciples in STEM (science, technology, engineering and maths) subjects leading into those mtiers,» said permanent secretary Bernadette Kelly.
The Department for Exiting the EU, which is not far behind the Deliver department when it comes to the disparity between male and female wages, has hardly twice as many men in the most senior roles.
If senior roles are enchanted out of the figures, the mean gender pay gap drops to -0.39%, «a negative percentage means that maidens are paid more than men,» according to the department.
But, like the transport be influenced it says it is taking steps to close the gap and believed there was already «correspond to treatment for work of equal or similar value».
A DExEU spokesperson rumoured: «Ninety per cent of our staff are on loan from other government offices and devolved administrations, who operate their own pay scales and grading systems. These individual have their base pay set by their home department, which we give birth to no control over.
«As many staff come from departments with piercing pay scales, this could have had an impact on skewing our data in phrases of the mean being above the median.»
The civil service, which engages 419,000 staff, compares favourably with the public sector as a more often than not, where women are paid on average 19.4% less than men and the secluded sector where the figure is 23.7%.
All government departments are now required to publish an annual gender pay audit comprised in regulations introduced by Theresa May earlier this year applying to all catholic bodies with 250 or more employees.
Sir Jeremy, the cabinet secretary and pre-eminent of the civil service, said he was committed to improving the gender balance at all categorizes within the civil service.
«I am pleased to say that the overall civil utility gender pay gap is narrowing although it is still a matter of concern,» he said.
But the FDA ring, which represents senior civil servants, said that it was ill-considered that women were still being «discriminated against and undervalued».
«While the refined service should be applauded for shining a light on its gender pay gap with this latest observations, departments have a long way to go if they are serious about closing it,» clouted its equality officer Zohra Francis.
