Plus there are new entries from Demi Lovato, Little Mix and Macklemore & Ryan Lewis.

Justin Bieber could be claiming his first UK Number 1 single this week as his latest single What Do You Mean takes an early lead on the Official Singles Chart.

Following an emotional performance of the track at the MTV VMAs last Sunday (August 29), the track leads the way on this week’s tally, pushing last week’s chart-topper Fight Song by Rachel Platten down to 2.

If he holds on to his lead until Friday, it will be Bieber’s first ever UK Number 1. To date, the star has 26 Top 40s on the Official Singles Chart, including 2012’s Number 2-peaking Boyfriend. Click here to view his full Official Chart history.
