American tennis pro Serena Williams has been announced as the newest ambassador of Allstate Foundation's Purple Purse initiative, which aims to financially empower the one in four women in the US who are victims of domestic abuse.

Williams commented 'Not a lot of people really know about financial abuse. It's an invisible but also really devastating form of domestic abuse that traps victims in these harmful relationships. If a woman’s credit is ruined, she can't get an apartment. Most of the time when people leave abusive relationships, they have this awful debt and that can take years and years to recover, especially if they have kids'.
