Number 10 is a drama series for BBC Radio 4 about a fictional British Prime Minister and his staff. The series was created by Jonathan Myerson, and produced by Clive Brill of Pacificus Productions, with Peter Hyman as Political Advisor. It has had five series to date, in 2007, 2008, 2009, 2010 and 2012. The first three series starred Antony Sher as Adam Armstrong, the Labour Prime Minister. The fourth series replaced him with Damian Lewis as a Tory prime minister in a minority government, in response to the United Kingdom coalition government which took office in 2010. "Myerson's radio play was Shakespearean in its intrigue, its moments of tragedy and comedy and in its multi-layered action....Sixty action-packed minutes led to a gripping denouement. Number 10 possesses the fast pace that is found in the best of TV drama, which radio has been crying out for.
