The Queen will sign the new Commonwealth Charter in an event on Monday after it received the support of every Commonwealth nation.
According to the Mail on Sunday, the charter which backs equal rights for women and gay people says:
We recognise that gender equality and women's empowerment are essential components of human development and basic human rights.
The advancement of women's rights and the education of girls are critical preconditions for effective and sustainable development.
The Government is introducing new legislation ending discrimination against women in the line of succession to the British throne.
The measure will mean that the Duke and Duchess of Cambridge's first baby can succeed to the throne, regardless of whether the child is a girl or a boy.
