The first of three brand new songs set to enter this week’s Top 40 comes from Zara Larsson - the Swedish star’s latest offering Ain’t My Fault starts at 27. The release follows her recent Top 20 hit with David Guetta, the Euro 2016 theme This One’s For You.

A new version of Black Eyed Peas’ Where’s The Love featuring a host of stars including Usher, Nicole Scherzinger and Jamie Foxx is at Number 30, and the song With You from the musical Ghost is at 32 following an emotional X Factor audition performance by Kayleigh Marie Morgan over the weekend.
