Midweek Charts update: Lily Allen overtakes Bastille and Barlow

Lilly Allen has pushed ahead of early front runners Bastille and Gary Barlow on her way to a possible third UK No 1 single on Sunday.

At the end of play on Wednesday it looked like either Virgin act Bastille's Of The Night and Polydor's Gary Barlow with Let Me Go would debut at the top this weekend with just 15 sales separating them, according to the Offciial Charts Company. But Allen has transformed the race with the Parlophone-issued Somewhere Only We Know now ahead of previous leaders Bastille, albeit by fewer than 200 sales up to the end of business on Thursday.

If it does make it Somewhere Only We Know, the soundtrack to John Lewis's TV Christmas campaign, would give Allen a third UK No 1 single after 2006's Smile and The Fear in 2008. It would also be the first No 1 single penned by Keane and the first for Parlophone since it was acquired by Warner. Allen and Parlophone are aso on course for a second Top 10 hit this week with her Hard Out Here new at 8 in the midweeks.

Below Allen, Bastille are now at No 2 in the week to date and Barlow at 3, while Polydor act Ellie Goulding slips 3-4 with How Long Will I Love You and Eminem's Interscope/Polydor single The Monster featuring Rihanna loses a place to 5.

On artist albums Robbie Williams' new Island set Swing Both Ways will on Friday surpass the total first-week sales of its 2012 predecessor Take The Crown on its way to debuting at No 1. It surpassed 80,000 sales on Thursday, around 50,000 more than its closest rival, EMI act Jake Bugg's Shangri-La, new in second place. Eminem's Interscope/Polydor-issued The Marshall Mathers LP 2 drops 2-3 and Celine Dion's Columbia-handled Loved Me Back To Life 3-4, while RCA act JLS's farewell Goodbye - The Greatest Hits is new at 5.

On compilations Universal and Sony's newly-issued Now! 86 is on the verge of surpassing 200,000 sales and continues to outsell the market's 50 other leading titles combined.
