<P> In an episode of the show recorded on 9 and 10 September 2001, Charles Ingram won the £ 1 million prize . During the recording it was noticed that a suspicious pattern of coughing could be heard . Ingram's unusual behaviour in the hot seat also drew attention . Analysed, it was believed that another contestant, Tecwen Whittock, sitting behind him, was offering him prompts in the form of coughs, indicating the correct answers . On some of the questions, Ingram read aloud all of the four answers, until a significant cough was heard, before choosing his answer . In some cases, he dismissed an answer, read aloud the answer choices again, and then picked the answer that he had earlier dismissed . It also appeared on the tapes that after Ingram repeated a particular incorrect answer several times believing it to be correct, Whittock coughed and then loudly whispered' No!' </P> <P> After Ingram won the million, Whittock won the next Fastest Finger game and so took to the hotseat . He reached the £ 4,000 mark, but dropped back to £ 1,000 after answering a cookery question incorrectly . </P> <P> The Prosecution suggested that Ingram's wife, Diana (who had won £ 32,000 on a previous show, as had her brother), had organised the scam . Pager telephone records revealed what appeared to be a practice session for another plan to cheat the system that was not subsequently carried out . The Prosecution claimed that the original plan was for Ingram to hide four pagers on his body that would vibrate when an accomplice called the pager indicating the correct answer . It would seem that during one of Diana's questions, an audible cough could be heard after Tarrant had read out all the questions to her, with the cough landing at the end of the correct answer . </P> <P> Following a trial at Southwark Crown Court lasting four weeks, Ingram, his wife Diana, and Whittock were convicted of "procuring the execution of a valuable security by deception" on 7 April 2003 . Ingram and his wife were each given suspended 18 - month prison sentences and fined £ 15,000, while Whittock received a 12 - month suspended sentence and was fined £ 10,000 . Together with legal costs, the Ingrams had to pay £ 115,000, in addition to not receiving his £ 1,000,000 . </P>
