Actors Jude Law and Thandie Newton have backed an ambitious campaign to tackle domestic violence around the world.
Organisers hope Peace Day on September 21 will set a world record in the reduction of incidents of domestic violence in a single day. Law is an ambassador for the charity Peace One Day which was founded by Jeremy Gilley.
Ahead of the London launch, the star of The Talented Mr Ripley and Sherlock Holmes said: "I've worked closely with Jeremy for a number of years, travelling to Afghanistan in 2007 and 2008 to document life-saving activities on Peace Day.
"The involvement of organisations working to counter domestic violence around the world will bring us another step closer to the institutionalisation of an annual Peace Day and I am proud to be supporting the process."
Baroness Scotland QC, founder and patron of Eliminate Domestic Violence (EDV), Moez Doraid of UN Women and other representatives from the Americas, Australia, Asia, Europe, and Africa were attending the launch.
Baroness Scotland said: "The Eliminate Domestic Violence Global Foundation is partnering with Peace One Day to support their Global Truce 2012 campaign for Peace Day 21 September 2012.
"Peace Day is as much about the violence in our homes, communities and schools, as it is about civil and international wars. For that reason, we have joined forces with Peace One Day to bring together a coalition of partners dedicated to reducing domestic violence worldwide, and together we will help decrease violent incidents on the day.
Mr Gilley said: "Peace One Day and EDV are asking all organisations from around the world committed to tackling domestic violence to join this process and come together to decrease the level of violence and generate a vast array of activity on Peace Day 21 September 2012 in support of Peace One Day's Global Truce 2012 campaign.
"We're hoping this will be the largest ever reduction of violence on one day - a world record."
