Margins to Mainstream with Michael Sheen spotlights 11 new writers from under-represented backgrounds on a journey to reveal truths from the margins of society. In episode seven, Michael introduces Becka White, a writer from south-east London and her mentor Ellen Peirson-Hagger of the New Statesman. The episode deals with imposter syndrome, something up to 90% of us feel. It doesn't matter if you're the first man on the moon or a new writer, like Becka. Her piece In At The Deep End deals with the fall-out of Thatcherism and you'll hear Michael Sheen perform it in front of a live audience at the Royal Welsh College of Music and Drama.
