Vernon Kay and Gabby Logan present the semi-final of the competition in which Olympic bronze medallist Tom Daley mentors a group of celebrities in mastering the art of diving. This week, the six contestants who made it through the first three heats will go head-to-head in a bid to reach next week's grand finale. The contestants are scored by Team GB diving coach Andy Banks, comedian Jo Brand and former Olympic diving medallist Leon Taylor, before the phone lines open for viewers to pick their favourite.
