The first contestant on the Great British Bake Off has left the competition after breaking down over a Swiss roll.

Claire Goodwin, 31, said she became "ridiculously worked up" over the cake and the pressure saw her burst into tears.

The fifth series of the culinary TV hit, with judges Mary Berry and Paul Hollywood, aired on BBC1 tonight for the first time, having moved from BBC2 following its huge success.

Mrs Goodwin said: "Getting myself ridiculously worked up about the Swiss roll was my worst moment. Why did I cry about a cake?

"I don't know why I did, but at the time you feel very passionate about it, and everything is magnified and seems more important than it is.

"But in real life, it is just a Swiss roll, and I had a bit of a laugh about it afterwards.

"My friend has got a mug made especially for me with the words 'I don't know why I am crying about cake... Claire Goodwin'."

Mrs Goodwin, a speech and language therapist from Cheshire, said her best moment was "pulling off" 36 chocolate cherry cakes even though they "exploded" and the judges labelled them "horrible".

She is now looking forward to watching the show from the comfort of her sofa.

The latest series of the culinary TV hit has its youngest and oldest contestants, with 17-year-old Martha Collison combining baking with her AS-level exams and coursework, while 69-year-old Diana Beard is the oldest baker so far.

The series is presented by Sue Perkins and Mel Giedroyc.

Mrs Goodwin will be joining Jo Brand on The Great British Bake Off: An Extra Slice on Friday at 9pm on BBC Two.
