Mary Berry will not be a judge on The Great British Bake Off when it moves to Channel 4, but Paul Hollywood has said he will remain.
Berry said she was staying with the BBC out of "loyalty", adding that it had nurtured her and the show.
She said Bake Off was "a unique and brilliant format from day one" and that she was "just sad for the audience who may not be ready for change"
But Hollywood said he was "delighted" to be staying on the show.
"It's been a huge part of my life in the past few years and I just couldn't turn my back on all that," he said.

Hollywood, who has signed a three-year deal with Channel 4, said: "I want to thank the BBC and Mel and Sue for making my time in the tent great fun and really rewarding."
He also thanked his fellow judge in a later tweet, adding: "She has made the right decision for her."

Love Productions, which makes the series, said: "We respect Mary's decision not to join the next chapter of the Bake Off story.
"We are immensely grateful to her for all her work and for her recognition today that Love Productions had made a unique and brilliant format from day one with Bake Off.
"The whole family, crew and team that made Bake Off for the BBC, and who will now make it just as brilliantly for C4, will miss her."
Mary Berry's statement:
"What a privilege and honour it has been to be part of seven years of magic in a tent - The Great British Bake Off. The Bake Off family - Paul, Mel and Sue have given me so much joy and laughter.
"My decision to stay with the BBC is out of loyalty to them, as they have nurtured me, and the show, that was a unique and brilliant format from day one. I am just sad for the audience who may not be ready for change, I hope they understand my decision.
"I wish the programme, crew and future bakers every possible success and I am so very sad not to be a part of it.
"Farewell to soggy bottoms."
Paul Hollywood's statement:
"Since I was a kid, baking has been part of my life. The seven series inside the tent have created some great memories. Best of all, I have felt so pleased to experience other people getting the baking bug, just as I did when my dad helped me make my first loaf.
"The Great British Bake Off has brought baking to the nation and we've seen people from all walks of life and backgrounds experience the highs and lows of competition, and more importantly helping each other.
"It's been a huge part of my life in the past few years and I just couldn't turn my back on all that - the bakers themselves, the bakes, the team that makes it, and of course the tent, the bunting, and who could forget… the squirrels.
"So I am delighted that I will be continuing as a judge when Bake Off moves to Channel 4. I want to thank the BBC and Mel and Sue for making my time in the tent great fun and really rewarding."
Charlotte Moore, controller of BBC One, said: "Mary is an extraordinary woman, loved and adored by the British public, and the BBC is her natural home, "adding: "I can't wait to cook up more unmissable shows with her in the future."

This Morning presenter Phillip Schofield tweeted: "Mary Berry quits Bake Off... clang went the wheels as they all fell off."
But Richard Osman, from BBC One's Pointless, wrote: "Boring truth is that Bake-Off will be just fine on C4. Won't be same show we love, and won't get same ratings, but will do a job for them."
It was announced last week that The Great British Bake Off was moving from BBC One to Channel 4. The network has signed a three-year deal with Love Productions, which makes the programme.
It is understood the corporation offered Love Productions £15m per year to keep the show on the BBC.
That would have been double the amount the BBC currently pays for the show and its sister programmes such as An Extra Slice and the Sport Relief specials.
But the company reportedly would not accept any offers below £25m.

"We made no secret of our desire for the show to remain where it was," they said in a joint statement.
Channel 4 will begin airing the programme in 2017, starting with a celebrity special in aid of Stand Up To Cancer.
The Great British Bake Off began airing on BBC Two in 2010, and quickly became a ratings success for the channel.
It grew in popularity each year, leading to its eventual move to BBC One in 2014.
Last year's final was the UK's most watched television programme of the year, with 13.4 million viewers tuning in to see Nadiya Hussein crowned the winner.
