Humphrys is a braying arse who long ago lost interest in his job and the people he's supposed to be interviewing, and Dimbleby's exterior is smooth because he is inflated to the point of bursting with self-satisfaction.Neither Dimbleby or Humphrys could be called offensive in the general way. That's not true of Moyles whose public persona really shouldn't be taxpayer funded or on prime-time media.
For a change I actually agree with the DM.
Give me Shelagh Fogerty, Victoria Derbyshire and Jenni Murray any time. And Simon Mayo who has found a new lease of life after DJing
