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?
