 Following the result of the series four final, which was won by Leon Jackson, media watchdog Ofcom received a number of complaints from viewers who said that they were unable to register their vote for Rhydian Roberts, despite trying up to ten times.After complaints topped 1,100, ITV issued a statement which assured viewers that "Leon won "The X Factor" fair and square" and did so with a winning margin of 10%.A subsequent Ofcom investigation found that Roberts had not been unfairly disadvantaged and that 99% of viewers that called couldn't get through to vote for Roberts, compared to 100% for Jackson.
