The "honourable" Dr M (he has a doctorate, but it is from the University of Made It Up).
Simon Andrew Hicks Mayo (born 21 September 1958, Southgate, London) is an English radio presenter who has worked for BBC Radio since 1981. As of January 2010, Mayo is presenter of Simon Mayo Drivetime on BBC Radio 2 and, with Mark Kermode, presenter of Kermode and Mayo's Film Review on BBC Radio 5 Live. In 2008, Mayo was recognised as the "radio broadcaster of the year" at the 34th annual Broadcasting Press Guild Awards and the "Speech Broadcaster of the Year" at the Sony Radio Academy Awards, receiving the latter for his "ability to paint colourful pictures of location and event and his ability to bring the very best out of his guests, encouraging conversation and interaction between them while skilfully nudging and controlling them" and for being "a master of light and shade, handling serious and lighter issues with aplomb."
