David Cameron's made the announcement at the 'Girl Summit' in London aimed at mobilising domestic and international efforts to end FGM and child marriage.
Mr Cameron told international politicians, campaigners including the Pakistani teenager Malala Yousafzai, and women who have undergone FGM who were at the summit that he wanted to "build a better future for all our girls" and that he was hosting the Girl Summit so that "we say with one voice let's end these practices once and for all".
"All girls have the right to live free from violence and coercion, without being forced into marriage or the lifelong physical and psychological effects of female genital mutilation. Abhorrent practices like these, no matter how deeply rooted in societies, violate the rights of girls and women across the world, including here in the UK", he said.
A new report out today from City University London in collaboration with Equality Now estimates that approximately 60,000 girls aged 0 to 14 years old were born in England and Wales to mothers who had undergone FGM.
It estimates that approximately 103,000 women aged 15 to 49 and approximately 24,000 women aged 50 and over, who have migrated to England and Wales, are living with the consequences of FGM.
In addition, approximately 10,000 girls aged under 15 who have migrated to England and Wales, are likely to have undergone FGM.
Speaking from the event on Premier's 'News Hour', Dr Anne-Marie Wilson from Christian charity '28 Too Many', which campaigns against FGM urged Christian leaders here to do more to end the practice, she said: "we know that communities that come from overseas to be part the population of Britain will carry on cutting or taking their daughters back home to the motherland to be cut. That means we've got girls who are in our schools, our youth groups our Sunday schools who are at risk of FGM".
Major steps to stamp out these practices to be announced today include:
-A £1.4 million FGM Prevention Programme, launched in partnership with NHS England to help care for survivors and safeguard those at risk.
-New police guidance from the College of Policing and an inspection programme by Her Majesty's Inspectorate of Constabulary (HMIC) that will look at how the police handle cases of FGM.
-A consultation on proposals to introduce new civil orders designed to protect girls identified as being at risk of FGM
-New legislation that will mean parents can be prosecuted if they fail to prevent their daughter being cut
-New legislation to grant victims of FGM lifelong anonymity from the time an allegation is made.
-A new specialist FGM service which will include social services, to proactively identify and respond to FGM; this will be supported by an ongoing package of work led by the Chief Social Worker Isabelle Trowlernew programmes to prevent child and forced marriage in 12 developing countries
-An international charter calling for the eradication of these practices within a generation.
