Why more and more women are losing custody battles over their children

Like millions of women of her generation, Karen Martin dared to believe that women really could have it all.

A high-flying creative director at a London advertising agency, she got married, had two children and while her husband, Mark, played the house husband, she was the family breadwinner.

For a while, this very modern arrangement appeared to be working out perfectly.

Then her husband had a fling with a single mother he met at a playgroup and Karen threw him out.

What followed was a traumatic court battle which saw a judge hand custody of her eight-year-old son and six-year-old daughter to their father, who lives on benefits in a council house.

To add insult to injury, the judge ordered Karen to pay maintenance to her former husband.
