Contributor(s): Diane Coyle | Acting BBC Trust Chair Diane Coyle considers how the BBC can meet the challenge of providing a universal service while media channels proliferate and its audience becomes more and more diverse. She will also examine the BBC's relationship with the state and ask how its independence is best protected. Born and raised in the North West, Diane was educated at Oxford and Harvard, where she did a PhD in economics. She has worked as an economist and journalist. Economics editor for The Independent for eight years, she left in 2001 to set up her own consultancy specialising in the economics of new technologies. Diane was a member of the Competition Commission from 2001 to 2009, which has given her extensive experience in understanding how markets work and how to make competition serve consumers. She has also written many popular books on economics. In 2009, Diane was awarded the OBE for services to economics. She lives in London and is married to BBC technology correspondent Rory Cellan-Jones. A BBC Trustee since November 2006, Diane was appointed as Vice Chair from May 2011 and Acting Chair in May 2014.
