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?

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?
