Last night, Ed Miliband gave a keynote speech about gender and equality in which he promised that a Labour government would ensure that children were given relationships education from the age of five - good news for Mumsnetters, who have been pushing for this for a while.
He also argued that our culture needs to change how it portrays women; in today's guest blog, he expands on why he thinks the representation of women is in crisis - and why it matters.
"Our banknotes are about to change. Not a major political issue, you might think. But it does have one important effect. Winston Churchill is going to replace Elizabeth Fry on the £5 note. And that means that everyone who will appear on our banknotes - apart from the Queen, our Head of State - will be a man.
I am worried about what kind of signal that sends. I read this week that the people who make these decisions think it is OK that there will be no women on our banknotes, because Jane Austen is "quietly waiting in the wings" to appear on her own note one day. But 100 years on from the great struggle to give women the right to vote, women shouldn't be "waiting quietly in the wings" for anything, should they?
Why don't we have one of our great women scientists, like Elizabeth Garrett Anderson, and a suffragette like Emmeline Pankhurst on our banknotes already?
This is a small but important symbol of the kind of country we are. In fact, I think it reveals a crisis in the representation of women more generally in our society.
Of course, greater prominence is given to fantastic role models for women and girls today than was true in the past. People like Clare Balding, Doreen Lawrence, J.K. Rowling, Jocelyn Bell and Burnell. And it is not just these people who provide role models for the next generation. My kids will grow up with Dora the Explorer as much as my generation did with Dennis the Menace, and that matters. And this week we have been supporting Laura Robson just as much as Andy Murray at Wimbledon.
But we should not be fooling ourselves by denying the problems. It is not just the absence of women from our banknotes or the way men out-number women in the statues on our streets. There are problems in our everyday culture too.
Young people talk a lot today about the problems of a culture that is tolerant of increasingly sexualised images. They are especially worried about a culture that says that girls will only get on in life, if they live up to the crudest of stereotypes. A culture where pornographic images, some violent, are available to children at a click on a smartphone or a laptop.
In discussing this problem, one young woman, 15 years old, wrote in to the Everyday Sexism site recently. She said: "I wish people would think about what pressures they are putting on everyone, not just teenage girls ... I wish the people who had real power and control of the images and messages we get fed all day actually thought about what they did for once."
She was right. There are things that government can do about it, like safer default settings on our computers. But that young woman's point is different. She believes there is a responsibility on all of us to do what we can to counter these images and to provide a better example for the future.
So, for example, schools should offer proper relationship education at all stages to ensure all our children have a proper chance to understand what good loving relationships are about. And they should always encourage the aspirations of girls and boys.
And advertisers and magazines should change the way they act too. We all know there are still too many images in our advertising that reflect outdated ideas about the role of men and women, boys and girls. And it matters how people are seen. About the images we have of each other. It sets an example, especially for the next generation.
Women face all sorts of injustices in our society today, many of which go far beyond our culture. There are still far too few women MPs, too few women in our boardrooms, the Cabinet or in senior management positions. Women have suffered more than men during Britain's recent economic troubles too, with this government's cuts affecting them three times as hard as men.
We need to act on all of these. But as we do so we must not forget the importance of cultural representation too. Many of these issues cannot and should not be decided by parliament or politicians. But it is something we must all talk about, as citizens and, especially, as parents. This is something that a new wave of young women are campaigning on, and talking about. They are right to do so and we should listen to their voices - that means politicians, advertisers, business leaders, and newspaper editors.
We can only be One Nation if we have real equality between men and women."
