Presenting duo Sue Perkins and Mel Giedroyc will not return to host The Great British Bake Off when it moves to Channel 4, a spokeswoman confirmed.
The duo have fronted the show since it first aired on BBC2 in 2010, alongside judges Mary Berry and Paul Hollywood.
A joint statement said: "We were very shocked and saddened to learn yesterday evening that Bake Off will be moving from its home. We made no secret of our desire for the show to remain where it was.
"The BBC nurtured the show from its infancy and helped give it its distinctive warmth and charm, growing it from an audience of two million to nearly 15 at its peak.
"We've had the most amazing time on Bake Off, and have loved seeing it rise and rise like a pair of yeasted Latvian baps.
"We're not going with the dough. We wish all the future bakers every success."
Bye Mel and Sue, we'll miss you.
