Kirsty Young's castaway is the baker and winner of The Great British Bake Off in 2015, Nadiya Hussain.

One of six children born to Bangladeshi parents in Luton, it was her father - a restaurateur - who encouraged her to cook. Having grown up in a culture where dessert wasn't common, her love of baking was awakened by her Year Ten home economics teacher.

She had an arranged marriage to Abdal in her early twenties and stayed at home to bring up their three children until her husband encouraged her to apply for the Bake Off. She was selected and over 15 million viewers watched her beat her fellow finalists Tamal and Ian.

Since winning Bake Off, Nadiya has been writing a column for the Times Magazine and has published her first cook book. She also has further books and a TV programme in the pipeline.
