Has anyone ever won one of those ITV competitions?

I was just watching The Voice and their competition has a prize of £40,000. Some of the daytime ones offer £100,000 in cash plus a BMW. I don’t usually bother entering but I thought, what a nice amount and wondered who actually wins and what the odds are.

Two of my co workers went on Supermarket Sweep (aired in August but can't remember when it was filmed) and won the cash prize!
