Week seven of The Great British Bake Off is Italian week. Prue Leith and Paul Hollywood have set three Italian challenges to test the six remaining bakers. There's a Sicilian signature that gets them all hot under the collar; while it's a toss-up as to who will survive the deceptively tricky technical. And finally there's a fiddly showstopper in the hottest temperatures ever recorded in the tent. Who will keep their cool and win star baker? And who will be saying ciao to the tent?

Our five bakers are stepping back in time and using unfamiliar recipes for Forgotten Bakes week. There's a sweet and savoury signature challenge and Prue sets a boozy technical.

It's the semi-final of the Great British Bake Off, and the four remaining bakers are all desperate to claim their place in the final. The remaining bakers know they are just three patisserie challenges away from the biggest day in their baking lives. First comes the signature, and there's no business like choux business as the bakers must set to work on producing 24 exquisite choux buns. Prue has set a complex technical for her first semi-final that leaves everyone stumped. And there's a meringue sculpture showstopper where the bakers mustn't crack under pressure. Who has the skill to reach the Bake Off Final and who will leave the tent?

Noel Fielding and Sandi Toksvig present this year's grand final, as the three remaining bakers compete to impress judges Paul Hollywood and Prue Leith and take home this year's trophy. For the final three challenges, they must prepare a batch of loaves, followed by a biscuit bake, and climaxing with a delicate, multi-layered, high-end patisserie showstopper to decide the winner.

In the fourth episode, presenters Noel Fielding and Sandi Toksvig welcome a new batch of celebrity bakers - comedian Lee Mack; writer and actor Griff Rhys Jones; TV presenter Melanie Sykes; and comedian Joe Lycett. The celebs face three tricky challenges set by judges Prue and Paul - with a blondies signature challenge; a testing technical; and the opportunity to reveal their secret passions with their cake showstopper. With tensions running high and confidence crumbling, who will demonstrate baking brilliance and be crowned star baker? They're all baking to inspire viewers to do the same, and to raise money for Stand Up To Cancer.
