LONDON, July 18 (UPI) -- The BBC suspended phone-in competitions Wednesday after the British network's probe revealed programs, including fundraising events, faked winners.

On each occasion, the "winning caller" was a member of the production team posing as a viewer, The Daily Mail reported Wednesday. Some of the shows featuring the sham winners included charitable fundraisers "Children In Need," "Comic Relief" and "Sports Relief."
