The Government will today pledge to donate more than £1 billion to help family planning services in the developing world.
In a bid to help 24 million girls and women in the world's poorest countries, British aid will be doubled for eight years, International Development Secretary Andrew Mitchell will announce.
Mr Mitchell will make the announcement as health leaders from around the world gather at the London Family Planning Summit.
The summit, which is hosted by the Government and the Bill and Melinda Gates Foundation, also aims to encourage poor countries to develop their policies to support the rights of women.
