Lessons on sex to be compulsory
Lessons about personal, social and health matters including sex are to be compulsory in all England's schools for the first time.
The government is setting up a review of how best to achieve this, saying there are "complicated issues".
Schools Minister Jim Knight said this would factor in a school's ethos, pupils' needs and parents' values.
A BBC poll of more than 1,000 people found two thirds would support sex lessons from the age of 11.
A review of the subject of PSHE was ordered after ministers said teaching was "patchy".
Until now it has only been compulsory to teach children about the biology of reproduction and changing bodies.
In Wales, sex and relationship education is already part of the curriculum and it is a legal requirement in Northern Ireland.
There is no legal requirement in Scotland.
The UK has the highest teenage pregnancy rate in Europe with 27 births per 1,000 women aged 15-19.
The UK Youth Parliament says four out of 10 young people say they received no relationship education at school.
Ministers said they were concerned that there were some serious gaps in young people's education, especially when it came to subjects like sex and relationships and drug or alcohol misuse.
