Then there is this study which came out this year.

"Women graduates are paid less from the very beginning of their careers, with men earning ?1,000 more than their college classmates within three years of leaving university, according to a major study published today.

Previous research by the Equal Opportunities Commission has shown a national pay gap fuelled by the tendency of women to slip into part-time roles after having children and work in areas such as childcare and cleaning which are paid less.

But these findings suggest that women are paid badly even in fulltime graduate jobs and even before they start to have children, take time out and fall behind in their careers."
