Lily Allen has returned to the top of the UK singles chart with her cover version of Keane's Somewhere only we know The song, used in a festive television advert for department store John Lewis, is tipped to be Christmas number one. In the album chart, One Direction have hung on to the top for a second week with Midnight Memories. Former X Factor winner Leona Lewis scraped into the top 25 with her cover album Christmas With Love. She was just beaten by Britain's Got Talent finalists Richard And Adam, whose Christmas Album debuted at number 24. However, it was a poor week for high new entries on both charts. Struggling to displace Allen in the singles chart were One Direction with Story Of My Life, Bastille's Of The Night and last week's number one, Under Control by Calvin Harris, Alesso and and Hurts. Gary Barlow's Let Me Go was unmoved at number five. BBC
