A flash-mob of dancers launched the One Billion Rising campaign in Parliament Square this morning as V-Day, a global activist movement to end violence against women and girls, marked its year-long campaign.
Today, women and men in 206 countries are expected to come together in the largest day of mass action ever to stop violence against women and girls.
The campaign, launched on Valentine's Day last year, began as a call to action based on the staggering claim that one in three women on the planet will be beaten or raped during her lifetime.
With the world population at seven billion, this means that a billion women could be subjected to violence.
