The future of celebrity Penn resident Mary Berry is uncertain, TV bosses have admitted, after it was revealed that the star has not yet signed up to a new-look series of Bake Off.

Channel 4 has admitted that judges of The Great British Bake Off are yet to sign deals to move to the broadcaster after it won the rights to broadcast the hugely successful show - but would be "delighted" if they do.

It was announced on Monday that the BBC has lost the show, one of the jewels in its crown, after refusing to pay a reported £25 million a year to keep it.

Presenters Sue Perkins and Mel Giedroyc have announced they will leave the programme, saying they were "shocked and saddened" to hear it would move channels. 

But the future of the show's judges Paul Hollywood and south Bucks star Mary are still unknown.

So far only Berry has commented on the move, saying that decisions were out of her hands.

"I have no idea, anything that happens is nothing to do with my choice," she told The Sun Online.

Channel 4 has signed a three-year agreement with Love Productions, the producers of the popular baking programme, for the format.

Separate contracts for the presenters and judges have not yet been signed.

Have your say - how important is Mary Berry to the show?

A spokesman for the broadcaster - which will air the show from next year - said: "We would be delighted if the presenters and judges want to come to Channel 4."

Love Productions had said it had been "unable to reach agreement" with the BBC, which has broadcast The Great British Bake Off for six years.

A BBC spokesperson said the corporation would love to have kept Bake Off but that they were "a considerable distance apart on the money".

Under the new partnership the multi-award winning series will remain on free-to-air television.

The first Bake Off programme set to be broadcast on Channel 4 will be a celebrity version of the show in 2017, in aid of Stand Up To Cancer.

Channel 4 said they were "very proud" to be the new home for the series.

The show began on BBC Two in 2010 before moving over to BBC One in 2014.

Last year's Bake Off final was the most-watched show of 2015, with 15.1 million people seeing Nadiya Hussain crowned champion.

The return of the show in August set an audience record, as 10.4 million people tuned in for the first episode of the seventh series.
