Sherlock star Andrew Scott wins BBC Audio Drama Award 28 January 2013 Last updated at 16:19 Andrew Scott, best known for playing Moriarty in TV's Sherlock, has been named best actor at a ceremony honouring the best of BBC radio drama. Scott picked up the best actor prize at the BBC Audio Drama Awards for his role in Harold Pinter's Betrayal on Radio 4. Scott won the best supporting actor prize at last year's awards. At this year's event, hosted by David Tennant, Michelle Fairley was named best actress for her part in John Steinbeck's The Grapes of Wrath. This Is England star Vicky McClure picked up the award for best supporting actress for Radio 4's Kicking the Air. David Troughton was named best supporting actor for Singles and Doublets, broadcast on Radio 3. "Acting on the radio is challenging, inspiring, delicate and always a privilege," said former Doctor Who star David Tennant, who won best actor at last year's inaugural ceremony. Radio drama is often overlooked and undervalued next to its showier younger siblings on the television and in the cinema. Yet it is on the wireless that so many important and brilliant talents have been discovered and nurtured. The award for best single drama went to On It, Tony Pitts' play about a heroin addict. The Lost Honour of Katharina Blum, adapted from the novel by German author Heinrich Boll, took best series or serial.
