Ellie Goulding is No. 1

Ellie Goulding has topped the Big Top 40 chart after her new song was featured on a Christmas ad.

Ellie has covered Elton John's hit 'Your Song', which was last in the top 10 in 1970.  Ellie's version of the song is currently being used in John Lewis' Christmas TV ads.

Just hours after the ad aired during the X Factor last week, the song flew in to our live top ten and during the week climbed to No. 1.  Last year the retail giant featured Fyfe Dangerfield's 'She's Always a Woman' in their ads, which resulted in Fyfe spending 10 weeks in the Big Top 40.

With the ad now due to run throughout the festive season, Ellie is now being tipped as a favourite for this year's Christmas No. 1.
