I'm probably being a bit thick but can anyone explain something to me. I know a lot of programmes aren't "live" e.g. Bake-Off and X Factor because we see a bit of next week's episode at the end of the current one. DP says every episode is pre-recorded, and he's probably right but if so, how is the winner kept a secret as I'd have thought it would have been leaked.
Am I being stupid! Probably!
