Josef Craig, Britain's youngest gold medallist of London 2012, scooped the Young Sports Personality of the Year award.
Craig won the S7 400 metres freestyle at the Paralympics at the age of just 15.
Paralympic gold medallist Sarah Storey revealed that she is 13 weeks pregnant today and is expecting a baby on June 23. Storey, who is nominated for Sports Personality of the Year, said it was "an absolute honour" to be shortlisted for the award.
Olympic gold medallist Jessica Ennis told ITV News it was "exciting to be in the top 12" for Sports Personality of the Year.
Bookmakers have revealed a late flurry of bets on Jessica Ennis being crowned BBC Sports Personality of the Year.
Odds on the Olympic heptathlon champion taking the award have fallen from 9/1 to 4/1 in the last 48 hours, betting company William Hill said.
She is now firmly second favourite behind cyclist Bradley Wiggins, who is odds-on to win after his historic triumph in the Tour de France and gold in the Olympics time trial.
William Hill spokesman Rupert Adams said: "There is no doubt that momentum has swung away from Bradley and Jess is steaming up on the outside. The only question is has she left her run too late?"
