The UK Daily Mail:

Schools could be required to teach children about gay marriage, Government documents seen by the Daily Mail reveal.

Officials at the Home Office and the Department for Education concede that teachers may be under a legal obligation to inform children about same-sex marriage once it has passed into law.

Under the Education Act 1996, pupils must learn about the nature of marriage and its importance for family life in sex education classes.

Critics said the documents, released under freedom of information laws, demonstrate that plans to introduce civil marriage ceremonies for gay couples in addition to existing civil partnerships, could have far-reaching and unintended consequences.
