Graham, currently the mid-morning presenter at BBC Radio Leeds, is due to take over from Tony Livesey in the new year. It follows the announcement earlier this month that Tony is taking over from Richard Bacon on Radio Five Live.
Graham, who worked at BBC Radio Lancashire four years ago, said: “I'm absolutely thrilled to be coming back to Lancashire. It’s the station I grew up listening to and if I was going to do a Breakfast show anywhere then this is where I wanted it to be.
“It's an exciting opportunity and I'm looking forward to becoming the new voice at the start of the day on BBC Radio Lancashire."
Graham’s first show will be on 4th January from 6am.
