Video: Hay Festival 2012: 'I don't know why Moira Stewart isn't on television' says Kate Humble Moira Stewart, who was the first black female newsreader on television, quit the BBC in 2007 after more than 30 years working for the corporation. It was widely believed that she has become fed up with the BBC's alleged prejudice against older women. She returned to BBC News, reading the news for the Chris Evans Breakfast Show on the radio, starting on in 2010. Speaking at the Telegraph Debate at the Hay Festival, Kate Humble also said it is "easy" for female TV presenters to blame a stuttering career on a culture that judges them solely on their looks. In a wide-ranging talk at The Telegraph Hay Festival, the former presenter of BBC's Springwatch also talked about the challenges facing the countryside. She also said the UK will need to generate energy from wind to help keep the lights on.
