X Factor and John Lewis would appear to have come to a mutual arrnagemnet whereby a song from their advert is chosen by Simons act and then the advert is run by said company during the final, no doubt as a backhander, to ensure it remains in the public conscious to get the public to spend more money in voting.
Then on Extra Factor a blatant product placement is made by KH, offering DO a Nintendo for no appararent reason which conincidently is also being advertised by ex Factor contestants.
And they say X Factor is not about expolting the public !!
