Matt Lucas takes over from Sandi Toksvig as host for the 2020 series, alongside returning presenter Noel Fielding and regular judges Paul Hollywood and Prue Leith. The 12 contestants for this series have been required to form a social bubble due to Covid-19 lockdown restrictions. The contest begins with Cake Week, beginning with a signature challenge to produce a classic Battenberg. For the technical round, Paul sets the contestants the task of making a fruit sponge, and the final Showstopper Challenge gives the bakers a chance to express their creativity.

It's Biscuit Week and the bakers make a sophisticated fruit, nut and chocolate combination for the signature, produce two tropical technicals, and create an elaborate table setting showstopper

It's Bread Week, and the remaining bakers have a lot to prove in a sweet and savoury signature, a technical that honours the NHS, and an ambitious, artistic showstopper.

It's Chocolate Week and the bakers tackle a deceptively simple traybake signature, a technical packed full of chocolate and nuts, and a white chocolate celebration showstopper.

It's Pastry Week and the bakers put their stamp on a Cornish classic in the signature, go retro in the technical, and make a showstopping classic tart hidden within a cage.

Noel Fielding and Matt Lucas host the show's first ever Japanese week. For the signature challenge the bakers tackle a Japanese version of the Asian staple, steamed buns, while the technical round involves a tricky recipe involving multiple layers. The showstopper round is themed around kawaii - the Japanese love of all things cute.

It's 1980s Week, and the bakers put their twist on the classic quiche in the signature, tackle a retro treat in the technical, and keep their cool with an ice cream showstopper.

It's Dessert Week, and the bakers tackle a miniature cheesecake signature, a 17th-century technical and a showstopping jelly art dessert cake, for a place in the semi-final.

It's the semi-final. The bakers' patisserie skills are tested in a booze-soaked signature, a tricky technical and a delicate showstopper showcasing their finesse and precision.

The finalists pull out all the stops in a set-custard signature, a choccy-nut technical and a magnificent dessert tower showstopper. Who will win Bake Off 2020?
