The moves, made possible by the impending departure of Mark & Lard and Sara Cox's maternity leave, will mean changes to both the weekday and weekend line up.
Along with Colin & Edith's new weekday show, Scott Mills will be taking over from Sara Cox in the afternoons from the end of May.
Over the sports-packed summer months, The Breakfast Show's 'Comedy' Dave will be teaming up with Mark 'Chappers' Chapman from The Sara Cox show.
The pair will present a brand new weekend show covering all the latest sporting action from across the globe.
