Are increasing numbers of women marrying men for their money?
According to a new study more women are are marrying for money than did in the 1940s.
The author of the report, Dr Catherine Hakim, tells BBC Radio 5 live "there is this myth that women invariably choose to have a relationship of total equality".
Speaking to Victoria Derbyshire, Dr Hakim continues: "More and more women are choosing to marry men who are substantially better educated than them, and therefore have higher earnings capacity."
