Weekend breakfast presenter Rachel Burden is moving to weekdays to join Nicky Campbell as co-host of the main 5 Live breakfast show from May.
She'll take over from Shelagh Fogarty, who is in turn taking over from Gabby Logan on the 12-2 lunchtime programme.
There was previously speculation that the station were looking to find a big name to join Nicky, with reports suggesting TV presenters Julia Bradbury and Fiona Phillips were being lined up.
5 Live Controller Adrian Van Klaveren told staff in an email: "Over the last few weeks we've considered a number of people for the role but Rachel is ideally suited. She's a fantastic journalist and a great radio presenter with a natural warmth and a real connection with our listeners. I've no doubt that 5 live Breakfast both in London and in Salford will go from strength to strength with Nicky and Rachel together, building on the great work the programme's already doing (and the brilliant audience figures). Of course this leaves a gap on Weekend Breakfast – I haven't yet made a decision on that one."
He later added: "She's someone who loves radio and instinctively understands 5 live's audience. She and Nicky already know each other well and I'm sure they'll be a winning combination every morning."
35-year old Rachel joined 5 Live in 2003, after starting her radio career as a reporter at BBC Radio Suffolk before going on to present Radio Bristol's breakfast show.
Commenting on her new role, Rachel said: "It's a brilliant opportunity to join what is already a hugely successful team. Shelagh is the mother of all breakfast broadcasters and I can only hope to match the impression she's made on the early mornings of millions of people. My family is already gearing up for the move to Salford and I am really excited about working alongside Nicky and the rest of 5 live in our new home in Salford Quays."
Nicky added "Rachel’s a great broadcaster, a great journalist and a great friend. It’s going to be great."
Rachel will join Nicky for breakfast from 6am on Tuesday 3rd May 2011.
