The BBC’s groundbreaking documentary about a transgender teenage has picked up a BAFTA this week.

Titled I Am Leo, the documentary followed Leo, a 13-year-old boy, as he told his story, and how he encountered bullying from people who could not accept who he is.

Born a female, Leo has lived as a boy since the age of 5, and legally changed his name when he was 11.

The film is set across seven months, following Leo and his family as he undergoes hormone therapy, meeting other trans kids, and eagerly waiting for a new passport that confirms his real identity to the world.

The documentary aired last year, on on the BBC’s childrens’ channel CBBC, which is targeted towards an audience of 6 to 12 year olds.

This week it picked up a prize at the British Academy Children’s Awards in the Factual category.

On the award Leo said:

“I want to thank everyone who nominated I Am Leo for this award, and everyone involved in making it a success.

I’m really proud to have been given the opportunity to make so many people proud by telling my story, and being able to tell it in my way.

I would like to say a massive thank you to Nine Lives Media, and especially to Cat [Lewis] for giving me the opportunity.

To [Phil Niland and Lyndsay Rowan], who I spent much time with, for their support and encouragement, and keeping me motivated throughout the months of filming.

I would like to thank my mum for believing in me, staying positive, and being beside me throughout my journey.”

The now-teenage Leo added that sharing his story has helped many others – with a lot of young trans people contacting him for guidance.
