Of the top 5 candidates, 3 are white males and 2 are ethnic minority males.
Which means whites are underrepresented there. If you limit it to the top 4, they're still slightly underrepresented (by about 5%) but it's as close as you can get without hundreds of candidates.
For male, you've got the issue that we just had a woman prime minister, but beyond that there's the usual feminist fuck up of assuming that the issue of women being "Underrepresented" at the top is due to sexism against them, rather than sexism against men. (Women have more freedom to choose work-life balance, as such, more of them do so. Because of this, men end up working unhealthy hours more often and in higher numbers than those who would willingly choose to do so. Those extra hours result in being promoted more often to these levels.).
Notably, Theresa May does not have children. That was one reason she did not choose work-life balance as opposed to being a workaholic.
Just saying.
When men choose work-life balance, they end up worse off than women making the same choice.
To fix this issue in feminist terms, cut womens pay in half if they dare to take maternity leave at any point in their career, but give men 90% of their pay if they do.
Then promote people based on time spent at the office. Apparently, this would mean you are oppressing the men.
In the same way companies offer better wages in order to compete for talent, when it comes to women, they offer better maternity leave benefits. Whereas men are usually stuck at the statutory minimum (Which itself is lower for men compared to women.).
Imagine offering women minimum wage no matter what, and offering men higher pay based on talent and so on, and then turning around and being like "The men are oppressed.".
You'd think the person saying that was a lunatic, right?
Welcome to my world.
This same dynamic applies to politics.
People will tolerate a woman taking time off. They won't tolerate a guy doing the same.
Then when it comes time to make a decision on who should lead or run for office, well who has more name recognition? Who accomplished more? And so on.
