Ofsted's chief inspector has backed a teacher who has been heavily criticised for teaching students about same-sex relationships.
Protests have been taking place outside Parkfield Community School in Birmingham, after parents took issue with teacher Andrew Moffatt delivering the lessons.
Christian and Muslim parents have claimed the lessons promote the personal beliefs of Mr Moffat, who is gay, and the teacher also claimed he had been receiving threatening emails.

However, Ofsted chief Amanda Spielman said it was important for children to know that "there are families that have two mummies or two daddies".
"It's about making sure that children who do happen to realise that they themselves may not fit a conventional pattern know that they're not bad or ill," she told the BBC.
Assistant head Mr Moffatt is one of 10 finalists in the running for the Varkey Foundation Global Teacher Prize, which has a prize pot of £765,607.
The other nine finalists teach in Georgia, Brazil, the Netherlands, India, America, Argentina, Australia, Japan and Kenya.
