Great British Bake Off viewers will discover who will be crowned king or queen of the cakes – but what will the future hold for series seven’s winner?

Andrew Smyth, a 25-year-old aerospace engineer, Jane Beedle, a 61-year-old garden designer, and 31-year-old PE teacher Candice Brown will be hoping to beat each other to the title and be whisked off into a dream career of perfectly risen cakes, beautifully baked bread and expertly piped icing.

First, they will need to impress judges Paul Hollywood and Mary Berry with some showstopping bakes – something these six former contestants have already done.

Series one – Edd Kimber

Mother-of-three Jo stormed to victory in the second year of the show and launched a new career for herself on the back of her win.

Series three – John Whaite

John was just finishing his law degree when he took part in the show, but things took a very different direction for him when he won and swapped plans to become a lawyer for a life in the kitchen.

He has published two books – John Whaite Bakes At Home and Perfect Plates In 5 Ingredients – writes for The Telegraph, and is resident chef on ITV’s Lorraine.

John’s cookery school offers classes in cooking, baking, chocolate and patisserie, and he even has his own range of stylish mixing bowls and jugs.

Series four – Frances Quinn

Childrenswear designer Frances’s eye for style helped her to bag the title of series four winner, although the name many fans remember from that year is runner-up Ruby Tandoh.

Frances has published a recipe book, Quinntessential Baking, produced delicious treats for Quentin Blake, Clare Balding and the Tate’s Matisse exhibition, and regularly updates her blog with her latest creations.

Series five – Nancy Birtwhistle

As a retired grandmother-of-eight, Nancy can be forgiven for wanting to take things a bit easier than her fellow winners after being crowned queen of 2014′s kitchen.

She has still found time to write about the programme for The Telegraph and shares tips and recipes on her own website, but has not become a career baker in the same way as some of the show’s elite contestants.

Series six – Nadiya Hussain

Last year’s victor Nadiya was a full-time mother studying for an Open University course when she won her series, but now she has rocketed into the world of baking stardom with a recent TV series, The Chronicles Of Nadiya, and regular appearances on The One Show.

She has published two books – Nadiya’s Kitchen and Nadiya’s Bake Me A Story – and was even chosen by Buckingham Palace to bake the Queen’s 90th birthday cake.
