Bieber's What Do You Mean?, which became the U.K.'s fastest-selling single of 2015 and his first number there upon its release earlier this month (Sep15), was toppled by Sigala's Easy Love last week (11Sep15), but now he's back on top.

Sigala slides to number two on the new countdown, while Calvin Harris & Disciples' How Deep is Your Love? rounds out the new top three.

Meanwhile, Welsh rockers Stereophonics have scored their sixth number one album with Keep The Village Alive, narrowly beating out Bring Me the Horizon's That's The Spirit for the top spot.

The Libertines' new album Anthems For Doomed Youth rounds out the top three.
