Former LBC 97.3 presenter Paul Ross is heading back to BBC London to co-host the breakfast show with JoAnne Good, replacing Max Rushden.
Max has been in position for just six months, taking over from Jono Coleman who left to spend more time with his family in Australia. Now Max will resume other duties at the station.
BBC London 94.9's editor David Robey said: "Paul Ross is the perfect foil for Jo Good as they are both big personalities who are passionate and knowledgeable about London.
"Together they will get their teeth into the news and issues which matter to Londoners as well as giving our listeners something to smile about as they start the day. Sparks will fly in a good humoured way."
