"I don't agree with all-male leaderships. Men cannot be left to run things on their own. I think it's a thoroughly bad thing to have a men-only leadership"

Harriet Harman is expressing her opinion that all-male leaderships are not helpful. She believes that males should not be left to run things on their own, and that it is a bad thing to have a men-only leadership. She is suggesting that a more varied management is required, with both men and women in positions of power. This is because she thinks that males and females have different viewpoints and experiences, which both ought to be represented in leadership roles. She is likewise suggesting that men-only leaderships can cause a lack of understanding of the requirements of women, and can cause choices that are not in the very best interests of everyone. By having a more diverse leadership, she thinks that decisions can be made that are more inclusive and useful to all.
