Belgian DJ and dance music producer Lost Frequencies has notched up his first No 1 on the Official UK Singles Chart.

Are You With Me knocked last week's No 1 - Tinie Tempah's Not Letting Go (ft. Jess Glynne) down to No 2.

Rita Ora had a new entry at No 3 with Poison while Walk The Moon's Shut Up And Dance was a non-mover at No 4.

The top five was rounded out by Major Lazer x DJ Snake with Lean On (ft. MØ).

Meanwhile over in the Official UK Albums Chart there was a new No 1 for Lionel Richie And The Commodores with greatest hits package The Definitive Collection.

The re-entry was prompted by Richie's triumphant Sunday daytime set at Glastonbury last weekend.

Glasto headliner Florence + the Machine slipped one spot to No 2 with How Big, How Blue, How Beautiful, while James Bay rose three spots with Chaos And The Calm.

Taylor Swift was a non-mover at No 4 with 1989 and her pop pal Ed Sheeran also remained static at No 5 with X.
